Reviews for Melatonin

Robb July 3, 2021

For Insomnia: “I have used Melatonin for insomnia, it helps me to fall a sleep faster, but frequent urination from 5am wakes me up which is not normal. Then in the morning feeling anxious and depressed for no specific reason, dizzy and tearful all day, fatigue and tiredness all day, unable to take my simple daily walk on a beach. Questioning my life and very dark mood. Nausea and no appetite all day, sleepy all day, headache. I took only 2.5mg for 4 days and then stopped. Feeling fine after 2 days. During these two days felt very dizzy, nauseated and tired. To be sure it was that I did test it once again month later, took only 1.25mg for 3 days and each day was worst then day before. It doesn't matter on the dosage, both times, I feel bad with all side effects above. I found out much better alternative is Magnesium Glycinate supplement which does not have any side effects on me, simply took 100-200mg pills magnesium and fall a sleep within an hour and slept well till' morning with no side effects next day.”

Melatonin Time Release (melatonin) for Insomnia: “I am on prescription circadian 2mg prolonged release melatonin and have not had any side effects. I have been unable to sleep due to damage to my own melatonin production due to 19 years of being on high dose of antidepressants. I can't produce enough melatonin. I thought my body would sleep eventually, but no. Longest was three days of being awake, losing cognitive function and having to turn to sleeping tablets, which only worked short term. This medication has saved me. I will be on this long term (with dr monitoring) After reading other reviews I feel this medication only seems to be helpful with sleep phase disorders when your body is not producing melatonin at the correct time, or for people like me who don't produce effective levels of melatonin to create sleep. In people with normal levels who have insomnia for other reasons it seems ineffective. It would be like people who don't have diabetes taking insulin to feel better. ”

For Insomnia: “Many people dose this medicine far too high. 5mg and above is absurd. 0.3mg-1mg gives me a beautiful nights rest. 2mg and 3mg and I was waking up every few hours. If you are having sleeping troubles while taking melatonin, try a lower dose! Higher dose does not mean better sleep, it can mean the opposite! Good luck”

slumber 52 · Taken for less than 1 month December 29, 2013

For Insomnia: “I am 52 year old female. My ability to get a full nights sleep has steadily declined since a hysterectomy 10 years ago. I am lucky to get 4 hours sleep a night. Occasionally, none. I tried everything, including prescription sleeping pills but quit them after 4 nights of use. Took two 3 mg tablets of natures bounty melatonin and was off to sleep in less than an hour. Slept well only woke couple of times during night but quickly fell back to sleep. Feel refreshed in the morning.”

For Insomnia: “Took 2mg melatonin last night to help me sleep and never again. I tossed and turned all night, had strange dreams but felt like I was half awake during them. Today I felt so flat and extremely anxious. It’s 2am and I’m still feeling anxious and just horrible. Having a camomile tea and hoping that it helps me. NEVER again”

For Insomnia: “I am a 97 year old man who loves to drink coffee and tea mixed together, its the only way I can swallow my viagra. Sometimes I can't sleep after doing the posturepedic polka. Melatonin is a blessing to me as I now get enough sleep.”

FoxSoup · Taken for 1 to 6 months May 25, 2021

For Insomnia: “I have had trouble falling asleep my whole life. I have had anxiety and a fear of bedtime due to all of the nights spent tossing and turning. I became accustomed to marijuana or alcohol as a sleep aid. I recently got a sleep tracker called Pura which shows exactly when different sleep cycles begin and end. This allowed me to clearly see what quality of sleep I was getting and what affected it. It led me to try different dosages of melatonin. It has completely changed my life. I now sleep effortlessly and get much higher quality sleep. Everyone will find a different formula. For me, the optimal dosage is a 3 mg extended release tablet. Any more than three and I would wake up drowsy with tingly fingers. Even 1 mg is enough to knock me out, though I get better REM sleep with the extended release.”

Frequently asked questions

Kylie May 17, 2019

For Insomnia: “I have Delayed Sleep Phase Disorder and taking Melatonin 2mg 5hrs in advance worked for me, I slept like a normal person for at least 2 months. Then suddenly I was having severe mood swings that could not be attributed to time of month and they got worse. I was flaring up with anger at the slightest thing and extremely harsh on two service providers that let me down. I was often angry for no reason and unable to control this constant feeling of being wound up. I didn't attribute this to the melatonin at first, but it had crossed my mind. Then, out of the blue, the melatonin simply stopped working, it no longer produced that wonderful drowsy feeling I would get before sleep (and have been missing most of my life) nor did it induce sleep any longer. I would be wide awake at 4am still after taking it at 5pm the day before. After a couple of weeks off it I noticed the aggression totally subsided. I would not use Melatonin again because it’s not worth the behavioural changes of severe mood changes. I would write more but there is a character limit.”

For Insomnia: “Had sleep problems a long time, especially regulating sleep patterns. Took 5mg of Melatonin for the first time last night. Within 30mins felt drowsy, went to bed and fell asleep immediately, woke up this morning feeling refreshed. Would certainly recommend and use again.”

For Insomnia: “I have been taking this for a week. I have anxiety, depression and panic attacks, and then after a Dr, change I was taken off my meds. So someone said take benadryl. Not a good Idea! I called ambulance when I could not stand the feeling of anxiousness and a paramedic said yes try melatonin when I asked because , heart racing, etc from benadryl . Well, not a good idea on my part either with melatonin! It is the same thing! Not as bad, but I sleep a couple hours, wake up all nervous and scared about health. I have started to cry at any little thing now. Have appointment with new Dr. But not for 2 weeks. I can't stand this! If anyone can recommend something safe please do!”

SC · Taken for less than 1 month August 27, 2019

For Insomnia: “Took Melatonin first time last night. To get sleep. Did not help at all for sleep. Woke up next day in a severe zombie-like severe depression. Found myself sitting in the sun and crying for absolutely no reason questioning my existence on this planet, asking God what's wrong with my brain. Then googled Melatonin side effects. BINGO causes major depressive episodes in those with history of depression..the funny thing is, to counteract the melatonin depression, was to uptake my vitamin D... my body told me to naturally sit in the sunlight to get vitamin d, before I even looked it up. Im glad my subconscious knew the natural remedy. Will never take this again. I couldn't even go to work today cuz how low I felt. Im throwing it away, and NEVER giving to my children anymore”

For Insomnia: “I am a 66 year old woman and have been taking Melatonin since 1990's. I started taking it for sleep since I had to get up early. There was never any side effects. I started out with 3 mg. Then went up from there. I always knew my limited because to much was creating just the opposite effects. I am now at 6 mg. and am doing fine. As we get older the meletonin that our bodies create, diminishes. Also, sleeping without a light or having a very faint night lite, is best. When getting up to go to the bathroom, do not turn on lights for lights depletes the meletonin in your body. I use a colored night light. And may I suggest just turning off your computers and phones so they won't interrupt your sleep.”

For Insomnia: “I had decades long addiction to Ambien. I decided it was time to get off and then my doctor gave me synthetic melatonin (circadin 2mg). I was told not to use 'natural' melatonin, as this was not 'regulated' and could contain a virus. I did fall asleep but the sleep is extremely light and I don't feel rested. I started having strange non sensual and upsetting dreams. It's 3 am right now, just woke up from a synthetic melatonin nightmare and I realized this is the problem with synthetic meds, it's not natural so your body doesn't know what to do with it. The synthetic meds gives you synthetic dreams and nothing about it is natural. It gets worse over time. I don't think I will take it any longer unless I can get the natural version which sounds risky. Now everything makes sense, at least why we shouldn't take synthetic meds a all, Your body battles a lot with it because it doesn't make sense to it at all. Stick to natural stuff rather.”

For Insomnia: “This melatonin was recommended by a paediatrician for our four year old daughter who was going to bed at 11 pm most nights and just couldn’t wind down. She is on 3mg, though as I purchased from USA online as it’s a lot cheaper than Australia, I also got a higher dosage, 5mg, for the rest of the family to try as we have all survived since her arrival on very little sleep in the household. This has been life changing for us and I researched the medication thoroughly as I was hesitant to give my child any medications though our experience has truly been exceptional with no side effects or issues as such. A wonder drug and one that I thoroughly recommend.”

For Insomnia: “I am 72 yo now and have never had any trouble falling asleep in the past until January this year when I became unable to fall asleep before 4 to 5 a.m. - every night and on a couple of occasions not at all! I was prescribed sleeping tablets but have not wanted to rely on them, so I tried anti-hystamine based tablets to try and help me sleep but they just left me feeling drowsy and wasted the next day. I then started on 3 mgs of melatonin about half an hour before going to bed and I am so pleased. They work beautifully. I get a good night's sleep and wake up refreshed the next day. I have not had any side effects from them either. They have certainly helped me.”

Ratpat December 2, 2013

For Insomnia: “It works well, although I feel depressed and super drowsy when I take too much. And when I don't take the pill, I feel like I can't reach deep sleep even if I was tired. Don't listen to the people taking 3 mg and over. That is way too much. The body produces 0.8 mg of melatonin naturally for your sleeping purpose. I take 1 mg at the max approximately 1 hour and a half before going to bed and keep functioning until I start feeling tired. I stay away from a screen with blue light.”

For Insomnia: “For Insomnia; I tried a 10mg and I was knocked out cold sleeping for my 8 hours right through the night worked amazing, so happy to find this instead of my dr having me taking 2mg lorazepam to sleep. Now I can stop the prescription and stick to a healthier way of sleeping. I find this works great highly recommended for sure.”

Bella · Taken for less than 1 month July 18, 2019

For Insomnia: “I have tried Melatonin 3 times. It is truly awful! It made me go into a very light sleep but it still felt like I haven't slept. It gave me headaches, very low mood, sadness, eye twitching, anxiety, weird dreams and felt completely out of it and dazed all day which isn't good for life or work. I'm going to seek natural methods. Never taking again. I heard today that staying really hydrated helps sleep. I'm also going to try the following: Valerian Root Lavender Oil Ginko Biloba Magnesium Passion Flower Tea”

For Insomnia: “Was prescribed melatonin by my doctor about 2 months ago. Due to anxiety, and tinnitus I hadn't been sleeping until around 6-7am or not at all. Having university the next day was a big pain, when I had no sleep and had to be able to focus for the rest of the day. I had been on many different medications before for both anxiety and insomnia, some of which worked but all had bad side effects. Melatonin works extremely well for me, with no noticeable side effects. I take 2 mg two hours before bed, and it works well. I normally get a good 7-9 hours sleep when I take melatonin and don't feel drowsy the next day.”

Eco January 18, 2015

For Insomnia: “I have been on prescription Ambien for over a year now. Last month, I decided to take a more natural approach to sleep. It was nerve wrecking at first, and I had terrible insomnia. Then I started taking melatonin. The first night I got a full 8 hours. As long as I keep a sleep schedule, this stuff is amazing. Note: take half your dose in the afternoon and half an hour before bed. Sleep at the same time each night.”

For Insomnia: “I have been trying melatonin for insomnia and it does help keep me asleep but has made my symptoms of depression much worse. (namely, slow brain activity, and suicidal thoughts). Just wanted to give a heads up to those who have depression to be careful. It is already mentioned here at Drugs.com that melatonin can have a bad effect on Depression.”

For Insomnia: “My son’s doctor recommended melatonin a few years ago because he really had a hard time falling asleep at night. He takes 1 mg before bed and falls asleep 10 minutes later. It’s worked great for him for 2 years with no side effects. I asked hm today if he wants to stop taking it and he said he hates tossing and turning so much that he wants to continue taking it. If you are having side effects, you should try cutting your dose in half.”

ms158 · Taken for 6 months to 1 year December 6, 2012

For Insomnia: “I've tried numerous prescription sleep aids. I'm on 50 mg of Adderall throughout the day so I definitely have trouble winding down at night. Ambien and similar prescription medicines only made the insomnia problem worse, buy adding hallucinations to the mix. A friend recommended I try Melatonin. It's fairly inexpensive, and if I take 3 about 30 minutes before bed I have a full nights sleep and feel rested in the morning. No weird side effects, like I experienced with the prescriptions I've tried. Works much better than Unisom or Tylenol PM. I suggest it to everyone I know having sleeping issues.”

Nowayhosay · Taken for less than 1 month April 27, 2020

For Insomnia: “Well. I have taken Circadin 2mg for three nights now. Dr prescribed these for me as for many years I have nightmares, talking, screaming in my sleep, thrash around night tremors in other words. Vivid dreams. Also take anti- depressants. No trouble falling asleep. Need to sleep 12 hours to feel normal as my dream life is so hectic! After taking this med, nightmares are worse!, heart is racing, waking up 2 am and like I've drunk 20 cans of Red Bull. Talking so fast I can't hear what I'm saying. Don't know what will work for me but this ain't the stuff! Never again!!!”

For Insomnia: “I took melatonin to switch my sleep schedule after working third shift. I was going to bed around 8am and waking up around 3pm. When I took one 12.5 melatonin I fell asleep around 12/1am, but woke up a few times throughout the night. One time I woke up, I was seriously down and the point of living for me was lost. I ended up crying myself to sleep. I have very mild depression that’s mainly work related. I never felt like this before. I’m assuming it’s from the melatonin. So, I’d recommend the with caution to anyone with any depression symptoms or diagnoses depression.”
