For Insomnia "I have used melatonin for insomnia. It helps me fall asleep faster, but frequent urination from 5 am 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 2.5 mg for 4 days and then stopped. Feeling fine after 2 days. During these two days, I felt very dizzy, nauseated, and tired. To be sure, I tested it once again a month later, took only 1.25 mg for 3 days, and each day was worse than the day before. It doesn't matter on the dosage, both times, I feel bad with all side effects mentioned above. I found out a much better alternative is Magnesium Glycinate supplement, which does not have any side effects on me. Simply took 100-200 mg magnesium pills and fell asleep within an hour, slept well till morning with no side effects the next day."

For Insomnia "Followed instructions, only took once. Fell asleep 2 hours after taking it. 11 pm. Slept for 6 hours but was getting up to urinate every hour, which is not normal for me. Very alert when I woke at 5 am. Had a cup of tea, and then the nausea, headache, anxiety, depression, and lightheadedness came on. My neck feels strange. Felt like I could throw up and no appetite. Would never recommend these."

For Insomnia "This particular brand of melatonin causes me to fall asleep quickly, but I wake up within half an hour feeling horribly dizzy, gassy, and nauseous. I also have vivid nightmares, and my general quality of sleep is far worse than non-assisted sleep. Give melatonin a try, but if your experience matches mine, you likely won't be able to continue."

For Insomnia "My doctor recommended 5 mg to help with some insomnia. I couldn't stay asleep. It had the opposite effect of what it should have done. Awoke feeling dizzy, nauseous, and also had a headache for most of the next day. I couldn't go to work the next day from feeling so sick. Definitely not for me."

For Insomnia "I've been taking this for approx. 2-3 months. It worked wonders! I can fall asleep anytime I want, which is great since I work a full-time night job and 5 hours beforehand at another job. So, falling asleep right away is key for me. But lately, I've been feeling dizzy, nausea, and a dull headache, which can sometimes turn into a migraine. And after reading these side effects, I'm wondering if it's the pills. I'm gonna try to stop using them to see if that makes a difference. Here's to hoping it works... but it'll suck as they have been very helpful."

For Insomnia "I had high hopes for this medication to reset my sleep cycle after illness threw it out. Unfortunately, the morning after I tried it, I felt hot and nauseated for several hours. I would suggest you try it on a night when you don’t have anything important on the next day in case it makes you feel unwell. Oh, and it didn’t help me sleep either, although I realize one night isn’t a sufficient trial."

For Insomnia "Made me slightly tired, but did not help me fall asleep. Also makes me pretty nauseous to the point that it is uncomfortable to sleep on my stomach."

For Insomnia "First time didn't make me sleep, and I felt nausea and dopey all the next day. I tried it months later one night and got severe headaches and didn't make me sleep."
