For Weight Loss (Obesity/Overweight) "I have been taking this for 2 months, and at first, I loved it. I lost 30 lbs in the 2 months, but then I started to get a lot of the severe side effects, such as a fast heart rate, dizziness, hard time breathing, chest pain, and insomnia. I really wish I didn't get these side effects, the pills were the best I have ever tried, but then it turned scary."

For Weight Loss (Obesity/Overweight) "After gaining 90 lbs through the last 4 years of nursing school, my heaviest weight of 277 lbs when I asked my MD for a prescription for Adipex. I started taking phentermine (Adipex) 37.5 mg daily every AM on May 9th and weighed in at 267.2 lbs May 17th, 266.1 May 25th, and 263.9 June 1st. I also do between 30-60 min strength training/cardio 3-4 times/week at the gym. After my first week taking this prescription, I did find myself needing to pay more attention to eating small meals 5-6/day or the side effect of dizziness would occur. Dry mouth is also a side effect, which I've noticed, so I bring water with me everywhere to get my fluids in around 3200 mL. I started taking half this dose the other day to decrease the dizziness, which has been effective."

For Weight Loss (Obesity/Overweight) "I started this supplement on October 29th. The first few days were a little rough for me. I had bad headaches, dizziness, nausea, and low energy. I worked out some kinks. I have to be sure I don’t take the medicine on an empty stomach. I usually have a protein bar just before it's time to take it or just after. The nausea, headaches, and dizziness have subsided, and my energy is picking up. I have not weighed in yet, but I feel confident that I have lost some weight. This is a good program; I have known several people that have successfully lost weight with it. Just hang in there; the first week may be a little rough, but it will get better. Also, I have not had any trouble sleeping at night, and I feel fabulous in the mornings. I have not overslept since starting the medicine, and that is normally a daily thing for me."

For Weight Loss (Obesity/Overweight) "I started phentermine (37.5 mg) on March 30th. I started out at 246 lbs. I am now down to 230.4! This pill does work! I have barely exercised, I eat 1 package of oatmeal in the morning, and for lunch and supper, I portion my food to about 1 cup. If I am not hungry for supper or lunch, I eat fruit. Drink lots of water, very dry mouth has gotten worse since the first week. The first day I had so much energy, and it felt wonderful! My side effects, which have been iffy but I've managed, are: dry mouth, occasional headache, trouble falling asleep, anxiety, tightness in chest, panic attack (only 1 day, and it was bad), tingling in arms, constipation (that's why I eat oatmeal every morning), dizziness. But the belly is going down and self-esteem is up!"

For Weight Loss (Obesity/Overweight) "I am 44 years old and have 4 kids. I am 300 lbs, my heaviest ever. I hate the way I look and feel. I just started taking phentermine 15 mg on May 30th, 2016. I do have high blood pressure and take meds for that. I haven't had dry mouth, but I did get dizzy 3 times and lightheaded. I do drink a lot of water during the day, and I take my pill in the morning. I only had 1 night that I tossed and turned. I really like taking meds, but I need help. I can't do it on my own. I just want to feel happy about my body, and I want to have control over the food that's killing me. Food is not my comfort anymore. I will overcome obesity!"

For Weight Loss (Obesity/Overweight) "STATUS UPDATE I stopped taking Phentermine on 5/3/2017 and was never able to get a prescription from my doctor until 10/6/2017. My starting weight this year was 243 lb, I started Phentermine 37.5 on 3/8/2017 with a weight of 237 lb and a height of 5'7''. On 5/3/2017, I weighed 219 lb and could not refill my prescription. On 10/6/2017, I went to my doctor to get the prescription filled, I weighed in at 210.2 lb. Up until the appointment, I was able to maintain and lower my weight with the help of diet and exercise mainly. Today is my first day back taking Phentermine 37.5, and I feel horrible. My side effects include feeling lightheaded, dizziness, a little nausea, and overall lethargic. I don't have an appetite but will force myself to eat soon."

For Weight Loss (Obesity/Overweight) "Today is the first day, and I do not like it. It did suppress my hunger, and I have yet to feel hungry since breakfast 8 hours ago, but I still ate a lite lunch. There are side effects for day 1. I did get a taste in my mouth, but it wasn't an unpleasant taste. Two hours after taking the pill, I felt a Nyquil kind of high. More like the next day hangover kind of feel. I did experience dizziness and was slightly jittery, but not much. Around midday, about two hours after the first rush, I felt another high rush hit, following dizziness and slight nausea... very slightly. I took the pill at 8 am, and it is now 4:53 pm, and I still feel the high/dizzy Nyquil hungover effect. After the second rush faded, it left me feeling drowsy."

For Weight Loss (Obesity/Overweight) "When prescribed, I really didn't think this was going to work. I have pretty much been overweight my entire life. My doctor recommended I take phentermine, mainly because diabetes was in my family history. December 31st, weighing 263, I began to take half of a 37.5 tablet. The first day, I was super dizzy for the first few hours. But I never felt that sensation again. I haven't really felt any symptoms related to the pill. Today I went in for my weigh-in, and I weighed 246, so a total loss of 17 pounds in 42 days. Although I wish it were a larger weight loss, I do have to take into consideration that I haven't really exercised. But my diet has changed radically. I would recommend giving it a chance. You never know what could happen."

Now, in the last six months, I've gained everything back! Starting my phen from today again! But feeling too dizzy and nauseous. Hope this won't last for long... Good luck, everyone!"

For Weight Loss (Obesity/Overweight) "I am a 22-year-old mom of 2. I have an almost 2-year-old and a 2-month-old, so I never got the chance to lose my baby weight with my first before I got pregnant with my second. I started phentermine on September 3rd at 193 lbs. Today is September 16th (1 week and 6 days after starting), and I am at 176! 17 pounds gone in just 13 days! No major side effects. I was dizzy the first day about an hour after taking it. Since then, no dizziness. Didn't cause headaches, insomnia, appetite suppression, or mood swings like people have said. The only thing that did happen was I get EXTREME dry mouth. And then I lick my lips to help, so now I have chapped lips too, lol. Drinking water really helps!"

For Weight Loss (Obesity/Overweight) "Started the drug 1/3/2018 and didn't make it the full month! I guess I won the lottery when it came to the side effects. Started with dry mouth, but I had energy, and the pill was working, so I thought I could deal with it. Around week 3, the fun started. Here we go: ringing in my ears/sensitivity to sound, hand tremors, numbness from my elbows to my hands, which made movement difficult, euphoria, dizziness, ABSOLUTE CONFUSION. I had trouble focusing when speaking to people and trouble forming sentences, flushed face, and intense jaw clenching. I am really bummed because I did lose 8 lbs in the month I was on it. Darn...."

I don't have dry mouth, but I did get dizzy and light-headed about 3 times now. One night I was tossing and turning all night. I do take my pill in the morning. I just want to feel good about myself and happy with who I am. I like this page because all the people write about how they are doing and that helps me to keep going towards my goals. I will post with results soon and hope to hear your stories. Thanks, Jeannie."

I am thinking to continue to lose my pregnancy weight of 19 lbs with a good diet and minimum exercise as I have a toddler. Can anyone suggest about morning coffee intake? Do I need to stop having coffee while taking these pills?"

I felt dizzy and a bit high after taking it yesterday, but haven't felt anything yet today. I barely ate anything yesterday, but I also barely slept last night. I am starting walking today and will post my progress."

For Weight Loss (Obesity/Overweight) "Started February 3rd. Wish I would've gotten to the review that said, 'Take 1/2 in the morning, the other half at noon to start ... lol.' Within an hour, I felt a bit of nausea, with a slight headache. I may be at fault because I'm so used to drinking coffee; I drank half a cup before I realized my mistake. Pros: Definitely decreased my appetite, felt a burst of energy for about 6 hours, no craving for sugar. Cons: Headache, not a throbbing headache, but just the annoying kind *(could be from withdrawal of coffee ... I usually drink at least 2-3 cups a day). Nausea. Little dizziness, slight dry mouth. Since weight loss is 80% diet and 20% exercise, getting an upper hand on my diet is crucial. I'll come back at the end of the month with another review. 58 years old, SW 220, GW 170. I'll be happy at 180 because I start losing where I don't want. I have a muscular physique (underneath the fat ... really I do). Hormones all over the place. Stay strong, ladies (and any gents)."

For Weight Loss (Obesity/Overweight) "I started phentermine about a week ago and have lost 3 lbs. I am only on 15 mg. My doctor made me drop 15 lbs before she gave me the prescription due to the fact that when you stop taking the pill, if you do not have good eating habits, you will gain your weight back and some. The first three days, I did not even think about food, but I am starting to feel like I want to eat again. I have been feeling dizzy some parts of the day. I am going to give this the 30-day trial, but I am praying it works."

For Weight Loss (Obesity/Overweight) "I started taking a half pill on Friday 10/6. The first day I was okay, just dry mouth. The second day was dizzy and out of it. Today is day 3. I have so much energy it's not even funny. I'm 30 years old, 5'5", 253. It's been 3 days, and I'm now 248. It doesn't seem real because I'm not on the pill. I am trying to eat better because I want it to work. I cut way down and just take it meal by meal. Being on this medication gives me anxiety because it's a controlled substance and it can be addicting. But I desperately need to lose a chunk of this weight, so I can have the motivation to do it on my own and keep it up! You guys all make me feel so much better with all your reviews, so keep writing!"

For Weight Loss (Obesity/Overweight) "I was 312 pounds when I started taking Phentermine 37.5 mg 11/2016. I took it for two months and only lost 12 pounds. I missed my appointment in February because my mom passed away. I went back to the doctor and weighed in at 306 pounds on April 6, 2017. Today is May 7, 2017, and I am 300. I lost down to 299 but have gained a pound because I haven't been drinking water and I haven't been active. Overall, I have lost 6 pounds in a month. That isn't bad for not exercising. The medicine is wonderful, but I am experiencing extreme dizziness to the point I am nearly fainting. I believe I need to drink more water. I have taken this medicine before and never had this problem, but I believe it's because I am dehydrated. Drink water!!"

For Weight Loss (Obesity/Overweight) "I started taking this pill on 7/30/10. I'm a 5'4", 25-year-old female, my start weight was 144 lbs. I've been going to the gym a minimum of 3 days a week (prior to the pills), 2-3 hour cardio classes. I was stuck on the same weight for a while, my eating habits aren't the greatest but not the unhealthiest either. I told my doctor that I had difficulties shaving off some pounds, so she prescribed me the medication. During the first week or so, I dropped 8 lbs. I'm at 136 lbs right now. My appetite has reduced immensely. I hardly desire to eat. I only eat small portions once or twice a day. The side effects that I have recently encountered for the past 3 days are a lot of dizziness (mostly when I stand up), lightheadedness, and some dry mouth (not too bad)."

I have vertigo, and this medicine only makes me slightly dizzy sometimes, but not bad. I am also taking Benadryl at night to sleep, because the insomnia is very real. I am loving this medicine, though, it works for me and so many others!"

"I started about a month ago (30 mg phentermine base). I have lost about 18 pounds. I'm 5'11, started at 218 pounds, and today I'm at 200 pounds. The first week I didn't lose any weight. Side effects: the usual dry mouth, some dizziness starting the second week, and then this goes away, but now I'm in my 4th week, almost 5th week, and I've been really irritable, and my mood really changed. I overreacted sometimes. I'll ask my doctor to decrease my dose since I'm presenting severe side effects, likely overdose effects. I still need to shed about 50 pounds and don't want to stop suddenly, but only if there's no way to stop these effects. Oh, and my menstrual cycle changed!"

Today is April 27, 2017, and I have lost 18 more pounds in 2 weeks. Total of 28 so far. I have no appetite at all, really. But I was starting to get dizzy and nauseous. Severe stomach pain, so I force myself to eat small meals. I do notice that I'm constantly thirsty. Easily agitated or annoyed also. But other than that, I like the results."

For Weight Loss (Obesity/Overweight) "I started taking them in May 2015. I weighed 196. First week I lost five lbs. I did get dry mouth, dizziness, constipation, and insomnia. Had to force myself to sleep. Doing Zumba with this pill and a Herbalife pill, with or without it together, I felt like my heart was jumping out of my chest when exercising. It did give me a boost of energy, but I started freaking out about it. Also, my bones, like the joints, started hurting. Think they warn you to take calcium or iron pills, vitamins. Month later, I'm at 182. After that, I would take half here and there, then stopped till October. Now I weigh 176. I've started researching cause of chest pains, tiredness, headache, all the negatives I've read when they were tested. Not worth the health risk."

For Weight Loss (Obesity/Overweight) "I am a 32-year-old mom of 3. I was at my heaviest ever-220. I decided I needed to change and stat! My doctor started me on the lowest dose back in December of 2014, and as of today (4-5-2015), I am currently down to 185. My goal weight is 160. He raised me to the highest dose of 37.5 daily. Today was my first dose, and at the gym, I had to cut it short because of being dizzy. I thought I was going to throw up as well. So, I went to the bathroom and fell on the floor. I slowly walked out and drove home. I took some Tylenol and laid back down for an hour. But still, 2 hours after the first feeling of this, I still feel dizzy and weak. I never experienced anything like this with the other doses. Is the dose possibly too high?"
