Phentermine for Weight Loss (Obesity/Overweight) "I’m so envious of those of you that this worked on! I have completed 2 months of this pill daily, and nothing. I did get some side effects the first week (faster heart rate, jittery, dry mouth, muscle clenching) and felt I was eating less, but clearly not. I still feel just as hungry, and I’m on the 37.5 mg dose! My dr told me to take a pill and a half to see if that helps, and so far it has not. I am so depressed as my eating is out of control. I am literally always hungry, which is why I needed help with the pill in the first place. I just wish I’d had the luck you all have had."

For Weight Loss (Obesity/Overweight) "As I mentioned in Part 1, the phentermine gave me so much energy. I began cleaning my entire house. The only side effect I remember was a very dry throat. I've only been on the pill for 4 days. I went to bed that night. I woke up with a rapid heartbeat. It scared me. I knew it was the phentermine. After the 2nd day, I haven't had any more rapid heartbeats waking me up out of my sleep. The pill is causing me to drink more water than I usually do. (LOVE IT) I got on the scale today. SW 180 lbs Nov. 8, 2017. CW 175 lbs Nov. 11, 2017. It really decreased my appetite. I haven't started exercising yet. I'm just eating smaller portions."

For Weight Loss (Obesity/Overweight) "I started taking Phentermine on 9/2, and in the first week, I lost 11 pounds! The second week, I did not lose anything, but we had to evacuate due to a hurricane, and even though I was never hungry when I did eat, it wasn't the best food for me. Plus, I don't think I thought to drink enough water. My third week (back at home), I am back on my 1300-calorie-a-day diet and tons of water. I have dropped another 3 pounds in 3 days. Side effects for me are dry mouth (real bad, but that's good for the water), jittery feeling (but not all the time), insomnia, and elevated heart rate after any kind of exercise. I should mention I haven't exercised much at all. 46-year-old female, starting weight 241 lbs on 9/2, and weight today 228 lbs 9/24."

Phentermine for Weight Loss (Obesity/Overweight) "I have been on Adipex for one week, to lose the last 30 lbs. (I have lost 80 on my own-but plateaued forever!). In the past week, I have lost 10 lbs. I am so excited to be closer to my goal. I never feel my heart racing or shaky, and I am one of the rare people that it helps relax. I have adult ADD. The first few days on the medicine, I took a nap-that never happens."

Phentermine for Weight Loss (Obesity/Overweight) "I started Adipex 37.5 on 3/8/18. So I've taken it for 3 days so far. Side effects so far are increased heart rate, this was a little scary to me at first, but apparently it's common. My resting heart rate went from 71 to 90. Also, increased urination when I haven't actually increased my water intake at all yet or when I hardly drink anything. I'm also a lot more emotional and cry easily, hopefully, this goes away soon. I have so much more energy, like I can't do things fast enough. I wasn't tired enough to fall asleep, but when I did fall asleep, it was easier to wake up after only 5 hours and make it through the next day with plenty of energy. I'll come back and update total weight loss at my 4-week check-in. Starting weight was 236, female, 5'3'', size 18 pants. Goal is 200, size 14 pants. I hold my weight well, and I'm pear shape, so I'm happy with my body at a size 14."

For Weight Loss (Obesity/Overweight) "I have been taking this medication for about 6 weeks and have lost 12 pounds, including 5 inches off my hips and 2 inches off my waist. I exercise 5 days a week. It is an intense workout, which includes cardio and weights. I do not feel as hungry all of the time like I did before. I drink a gallon of water a day, if not more. I have experienced a few side effects, like dry mouth, rapid heart rate, some constipation, and headache. I want to continue until I reach my goal and do not want to give up! Seems like in the past I always give up, but not this time. This works really well and I highly recommend this. I have 25-30 pounds more to go!"

Phentermine for Weight Loss (Obesity/Overweight) "Consumers, I've been on Fastin off and on for about a year now. I read most of the comments before posting my experience. I usually only take 1 in the morning before I worked out to give me the energy I need to complete my 5-mile walk. If I'm not working out that day, I take half of a pill due to the fast heart rate and slightly the jitters. To be honest, I haven't seen much of a weight loss. Could be I'll start for a week or 2 and then stop. My issue is I need to be consistent with working out and taking the pill to see results. I do believe they would work if taken properly. I read one comment, and the consumer said she lost 35 lbs, so that there is inspiring me to push forward to achieve my weight loss goal."

For Weight Loss (Obesity/Overweight) "Three years ago, I took phentermine 15 mg (per request) for my SW of 287 lb! It took me a year, with a couple of different ‘stop weeks’ of taking the pill to boost myself. I lost 60 lb and felt amazing! I stopped taking it for almost a year and just two days ago started again as I have upped 20 lb. This time my doctor prescribed 37.5. She said that it is safe to take as long as needed, as long as you lose weight and feel okay. (She attends obesity clinics quite regularly!) This time around, I am now on blood pressure meds, but I am going to closely monitor it now. Side effects of this medication are decreased appetite - yay! Noticed this day one. You do get energy, but make sure you take it as soon as you get up! Dry mouth is a downfall, but ya kinda get used to it, and more water intake is never bad! My heart is kinda racey at night, which I didn’t notice with the lower dose. It’s not constant, and I usually only notice it once I am laying in bed. I will update soon!!!!"

For Weight Loss (Obesity/Overweight) "I was prescribed phendermetrazine for the first week, and it made me feel awful! Bad headaches and made my heart pound. In my first week of taking it, I lost 8.5 pounds. I weighed 283 when I started and lost the 8.5 pounds and am now weighing 275. It has helped me to not feel hungry all day. But with the bad side effects, I asked to be put on phentermine and have had no side effects and a lot of energy, and my heart isn't pounding, so let's see if I get the same results. I'm super excited!!"

For Weight Loss (Obesity/Overweight) "I started on phentermine 37.5 mg almost 1 month ago. I was prescribed this in conjunction with another medication after visiting the doctor because I was experiencing constant unusual feelings of hunger. The doctor said he wanted to see me below 200 lbs - I started at 203 and now, after one month with phentermine, am at 198. I was excited to try it because I read all these reviews, and since I already have a good diet and exercise 3 times a week, I thought I would really see some results. I had the feeling of adrenaline and rapid heartbeat the first day only. It never kept me up at night. Dry mouth has been incredibly annoying, though it forces me to drink water... all the time. I've been eating a whole lot less than before but not seeing major results."

For Weight Loss (Obesity/Overweight) "I am a 44-yr-old woman. 4'11'' starting weight 169. I started on Dec 26, only taking a half dose of the 37.5 mg. I did this about a week. The first few days, I experienced insomnia and a faster heartbeat, but it didn't last long. I have lost 4 lbs. The first week, I was still eating more than I expected, but now it seems to be holding longer throughout the day. I am drinking a lot of water, partially because I have extreme dry mouth. I just started at the gym as well, so I'm hoping for some really good results in the coming weeks. I will continue this and keep updating. PS: One side effect I have noticed a significant change in is loss of libido. I hope this is not a lengthy side effect. :("

For Weight Loss (Obesity/Overweight) "I've been taking phentermine 37.5 for a while now. Since June 7, it is now July 20, and I have only lost 8 pounds. I don't have an appetite at all, I have to force myself to eat. I think it's only like 1000 calories a day, if that. I have really bad heartburn and have some insomnia. Other than that, I haven't experienced anything else. I am 5'6" and started off weighing 180, I'm down to 172. I did have an episode of jitters, tingly arms, rapid heartbeat, and cold sweats, but I ate an apple and felt much better. I'm not sure if the pill is actually helping me lose weight since I've been on it for 44 days and have only lost 8 pounds."

Phentermine "This is the best diet medicine ever. I have been taking this pill for years. I generally take it two days on and one day off for efficacy, and it has worked. When I first started taking this medicine, I did not follow any type of eating plan and would stop and gain all my weight back. That made me realize I had to use an eating plan of my choice, like Weight Watchers. Low carb diet is my choice. This pill has taught me how to eat also. I ate sweets all the time before this pill and now eat a sweet only the day I do not take the pill. I recently went off Adipex in December because my doctor feels my heart rate was high (103, 115, etc.). I went back on them and monitor my heart rate because I gained 15 pounds. No other medicine out there like it."

For Weight Loss (Obesity/Overweight) "Pros: Not too much stomach discomfort, even with an ulcer and irritable bowel syndrome, alters your craving for food - instead of fries, it's fruit. I've lost 82 pounds so far, with only 20 to go. Cons: It alters your cravings, not sheds the weight for you. It must accompany a change in lifestyle. I had trouble with increased heart rate, and I'm in my 20s with no heart problems. I was even unable to donate blood because the rate was too high. This stabilizes every time I go off the medicine. It also can make me restless. When my husband and I were both on it, we fought like crazy all the time. I thought I was crazy, but each time we would stop taking it, the fighting would decrease."

For Weight Loss (Obesity/Overweight) "I started taking 1/2 pill of phentermine 37.5 mg on April 3, 2018. I’m 49 years old, my SW was 205 lbs, and I’m 5’7”. I have been a yo-yo dieter for quite some time now, and nothing seemed to work. Carbs in the form of pasta and rice are my weakness. I would eat till I got full, and most of the time, it was 2-3 plates later. When I first took the pill, my heart rate did go up, and my chest didn’t hurt, but I felt it got tight. Followed the plan of eating low or no carbs and would eat my last meal before 7 pm. Didn’t work out at all, but just took the stairs at work. Fast forward to Sunday, April 8, 2018, weighed in at 196.5. That’s an amazing 8+ pounds lost in 5 days. I don’t know if it’s that little pill, but I’m definitely buying into it. It takes my craving completely. This is just a temporary fix and controlling what I eat. I’m so ready for this weight loss journey. Let’s go!!"

For Weight Loss (Obesity/Overweight) "I'm 20 years old, and I'm 5'3.5". I've just started taking Phentermine 37.5 mg on December 1, 2016. My initial weight I started out with was 255 lbs. I have no clue what my weight is now. But this pill I take gives me dry mouth and a slight fast heartbeat. Since I was 15, I've always been a big gal, and then when I was 16, I was diagnosed with high blood pressure and slight heart trouble. Well, finally, when I was 19, I was in Florida for a job at the Daytona500 Club. A week after my job interview in Florida, I woke up one morning feeling really sick. I went to the hospital for about five days. Then I said to myself, I'm too young to die, so I started dieting-no luck there on my own. So, I went to my doctor for help, so wish me luck. I'll update y'all."

For Weight Loss (Obesity/Overweight) "Standing at 5'3", I weighed in at 228 lbs Monday, Sept 14th, started phentermine Tuesday morning, Sept 15th. Within 20 minutes, I felt a rush come over me, my heart was racing, I was sweating, there was a numbing feeling in my arms, as well as I felt that I couldn't get the right words out, almost tongue-tied. Then, about 6-8 hours later at dinner, I kept feeling like I was moving in slow motion. Side effects: the verge of a headache, not one but could be triggered at any moment, dry mouth, and insomnia. I can usually only get 4-5 hours of sleep tops, which is extremely difficult with a 2-year-old. But I have already lost 3 lbs, I am keeping to a 1500-calorie diet. No exercising yet due to heart rate being elevated at simple movements! Will start next week! I'll keep posting."

For Weight Loss (Obesity/Overweight) "This is the second time I've used phentermine. After I had my third child, I used it to drop 20 pounds, and three years later, I have gained 10 pounds again, so I used it again. It definitely works, especially with exercise. You just have to take it easy, because your heart rate does seem faster, and drink tons of water. I drink about four or five bottles of water a day when I take phentermine. I have lost almost 15 pounds in two months' time - but again, I've been working out two times a week lifting light weights and 30 minutes of cardio a week. Great product!"

For Weight Loss (Obesity/Overweight) "I'm taking this medication because of an odd amount of weight gain relating to hypothyroidism and that in relation to my first and only pregnancy. I've gone from 135 lbs to 169 lbs in less than a year. I stressed this problem and was recommended phentermine. I've lost about 10 lbs since taking it a month ago. I eat half of my portion sizes. I consume lighter, healthier foods. More energy. Downsides to this new medication, though, are bad dry mouth in the afternoon. My heart feels like it's going to burst out of my chest depending on emotions. And sleeping! I'm usually up till 12, 2, 3 o'clock in the morning sometimes. Every day I'm awake inside, but outside I don't look so good. Going to continue another two months and see what happens."

For Weight Loss (Obesity/Overweight) "I’m 34, 5’1, and was at 158.6 pounds at my last doctor's appointment. I told my doctor I needed help losing weight, 158 lb was the biggest I’ve ever been, and it’s hard for me since I have a big appetite. I’m going on day 5 and am already down to 153 lb. The first day was rough, my heart felt like it was beating fast, and I was very jittery. I’m drinking only 8 oz of coffee in the morning and nothing but water throughout the day. I have oatmeal in the morning for breakfast and don’t have an appetite until dinner, although you should eat something healthy in between to help with the headache I was getting the first couple days, but now I’m fine, no more headaches and no jitters. I have shortened my portions at dinner and nothing else to eat after."

Now in 2009, I needed something to jump-start my weight loss. So I went to a weight loss clinic. The first day, I had a headache. I don't get excess energy, but I have no side effects. I'm just hungry now, but I eat 3 small meals a day and went from 209 lbs to 187 lbs, as weighed yesterday. I exercise daily and drink nothing but water."
