For Obesity: I am 165cm tall and was 76kgs when I started- my eating at the time had went out of control and I just needed a stimulant to get me kick started into being fit. After 2 months, I'd went down to 60kgs. The only side effect I had was dry mouth, which I compensated with lots of water. I also ate lots of raw vegetables to keep my bowel movements going. This was a year ago and I'd been off the medicines since. I'm currently 58kgs and down to UK size 8, from my old 14. I've kept the weight off by walking everywhere and watching what I eat, making sure not too snack too much like how I used to! From what I read everyone's experiences are different, but phentermine was just the kick starter I needed.

For Weight Loss: My experience with phentermine has been wonderful. Within the first 3 days of taking it, I lost 7 pounds. I haven't even been on it two weeks yet and I'm down another 7 pounds. I also watch what I eat, when I eat all the time. Calorie count EVERYTHING and exercise everyday for 30 minutes to 1 hour. Plus I am positively more active, increased sex drive and simply happy. I am scattered brain and dry mouth. I suggest lots of water and Green tea.

Adipex-P (phentermine) for Weight Loss: I have nothing but good things to say about this pill. The first time I was on it I started it in Feb of 2012 and stopped due to death of my mom in June 2012. My start weight was 210lbs and I am 5'6". When my mom passed I weighed 179lbs. I was supposed to be on the meds until September so I lost 49lbs in 4 months and I felt awesome. Until that day in June where my world came crashing down. I just recently went back on the pill weighing in at 205lbs and now I am down to 191lbs. It is working a little slower the second time around but now I am a stay at home mom of three and haven't really been able to exercise since I have been on besides my regular running around after the kids. No side effects.

For Weight Loss: I have been on/off of Phentermine since April 11, 2013. With all my breaks to break the plateau I have been on it combined total for 2 months. I lost 20lbs my first month without any breaks and lost 10lbs my second month. I mostly walked for my exercise. About 4-5 days a week. I quit drinking everything besides water. I ate a strict diet of only white meat, protein, veggies, and fruit. I rarely ate carbs and if I did it was whole wheat/grain. I have stalled so bad on my weight loss but haven't gained anything and have not been having a good diet. Starting tomorrow I will have been off of it for 1 month. I plan to start my last bottle tomorrow to drop my last 20lbs.

For Weight Loss: I started phentermine July 12,2013 at 195 lbs, on July 19th I weighed in at 186lbs, lost 9 lbs the first week. My pants are starting to fit me better, its so amazing. I eat healthy following my diet plan exercising 5 days a week 2 hours a day. My goal is to be 135 lbs. If you are thinking bout taking phentermine you should do it, just drink alot of water.

For Obesity: I started the phentermine tabs after I witnessed my aunt's results. I had 2 kids within 1.5 yrs gained 70lbs with my first lost 50lbs then found out I was pregnant again, gained 70 more lbs on top of the 20lbs so I'm up 90lbs. I tried everything, and many shakes. I went to my MD July 12th weighed 232lbs had my blood work done and EKG everything was a go started the next morning July 13, 2013 today is July 17, 2013 and I'm already down to 224.8, 7.2lbs in 4 days. I was jittery for about an hour the first day I took the pill but it went away quickly. Dry mouth I cure with water. I love the energy, I'm not tired when I get off work. Play with my kids, watch my late night T.V. shows and wake up refreshed. Can't wait to see my 3mth results.

For Weight Loss: I LOVE Phentermine! I started taking it May 1st 2013 I am 5'5" was at my highest weight, 187lbs. I drank sodas like crazy and ate nothing but greasy foods chips and other junk. My first week on the Phentermine I couldn't eat (which they said was normal but told me to force feed myself) and I drank nothing but gallons of water. I lost 12.5 lbs in just 7 days, Amazing! It is now July 10th 2013 I am 155lbs. Just started my 3rd month and already down 32lbs. It's the best diet pill ever. The only side effect I've had is dry mouth, which is actually a really good thing because it makes you drink tons of water. I have had absolutely NO cravings. It's just plain amazing. Definitely try it if you are struggling with weight loss.

For Weight Loss: I've been on phentermine for 17 days now and I started at 181 lbs. I weighed in a 168lbs this morning. I'm still hungry while taking it, but I don't eat huge plate fulls like I used too. Sometimes I eat very little, like 5 bites of food all day. I do not have increased energy, actually I was quite tired the first week. The second Week, insomnia. I actually stayed awake for over 24 hours one day last week. I'm 29 and haven't done that since I was a teen. No headaches or nausea. EXTREME dry mouth and diarrhea every other day, also whenever I stand up I have to do it slowly, I get dizzy every time and almost fall over. I work out 3 times a week to kickboxing but that's about it, besides chasing my kids around.

For Obesity: I started phentermine Feb 18, 2013. I had been going to the gym for years trying to get off this extra weight. Been over weight since I was 8 yrs old. I'm 24, 5'4, & got to my biggest in January (250lbs) I've always had high self esteem but at the point I didn't even want to see a mirror. When I started phentermine in February I dropped 10lbs in 2 DAYS! No lie! Because my body was not used to the medicine I was sweating profusely, heart racing, mad energy. Combined that with gym, was down to 235lbs by April. Sadly I started plateauing April & May. I had tried everything but stayed the same. Put up the resistance in my cardio & finally lost the 5lbs. Now it is July, & I'm out the plateau I am down to 220lbs! Goal is 160/170lbs.

Adipex-P (phentermine) for Obesity: I am just over halfway through my 3 month Adipex regimen and am feeling great. For anyone struggling with weight loss, I highly recommend asking your doctor about Adipex. My physician was very quick to prescribe it as soon as I asked about it, as he could tell I did my research. I am 5'5, 25 y/o, and started at 193.5lbs. The biggest pro about this medication is that it almost completely rid me of my uncontrollable cravings (I don't even think about chocolate anymore). With that out of the way, I am now able to more easily make healthy changes to my lifestyle. I have started eating more vegan-like and making being active part of my daily life. So far I am down 19.7 pounds. I feel like myself again!

For Weight Loss: Just want to share my experience on this medicine. I have taken a lot of diet pills throughout my life, to be honest with you, nothing had worked! I been taking this medicine for a week now and I had lost 5 pounds! It's a miracle for me and I was born with a generation of obese family background. Throughout my life my weight has been up and down, for the days that I ate a lot, more or likely I gained two pound. This medicine will cause you dry mouth and over active on the first day that you take but after awhile your body will get used to it. The most amazing thing is you have to force yourself to eat! After you eat some food, you will feel like extremely full. I only ate breakfast and lunch with this medicine. Just eat healthy!

For Weight Loss: I have been taking phentermine 37.5mg once a day for the past 37 days. My obgyn prescribed it for me to take for 90 days. So far I have lost 16.4 pounds. My highest weight was 222lbs which is a lot for my 5' 3" frame. My goal weight is to be at 140lbs. This has really helped jumped start my diet. I had little motivation to lose weight because I felt like it was so much! I couldn't believe how much I had put on through the years. I was constantly starting a diet and trying to eat right but not working out and getting frustrated from the results. I also have PCOS and gained a lot of weight from taking Zoloft for my anxiety. I am counting calories and working out and hopeful to see even more improvement with my remaining 53 days on the medicine.

Fastin (phentermine) for Obesity: I've been over weight all my life. I started recently getting really bad back pain and chest pains, I went on a scale and 287lbs! I was emotional, devastated and embarrassed! I've tried everything but I don't give nothing enough time. I don't have any patience. Tried Jenny Craig regular diets, diet pills, I had a personal trainer..nothing never worked. So started taking Fastin last Friday I'm not starving myself I'm eating fruits veggies, lots of water and so far 6 days later I've already dropped 8 lbs! I'm so happy I still have a very long way to go but I do recommend Fastin.

For Obesity: I started taking phentermine in late January of 2013 weighing 180lbs at a height of 5'4 as of June of 2013 I'm down to 139lbs. This is with me going through my final semester of college, college graduation, graduation parties and attending three different weddings. I don't honestly workout but am an active person doing things around the house (painting etc.) The main change I have made since starting phentermine was trying to eat healthier. No I did not have unflavored fish and rice or salads... actually I ate hardly any of that. I just checked the nutritional info on what I ate. I watched my portions meaning I ate only if I was hungry and stopped when I was full even if there was still food on my plate. I encourage anyone to try it.

For Obesity: I went to see my Dr. on June 3rd and I weighed in at 218lbs. I started on my pill on June 9th. Today I weigh 210lbs. I have changed my diet and cut out all of the burgers, fries, and cokes. My exercise consist of me walking on the track in the morning hours around 6 a.m. for 2 miles and at work on my lunch I will do 30 mins on the treadmill. The only side effects I have had so far was dry mouth and getting too sleepy. This is the best medication I've ever had for losing weight.

For Weight Loss: I am not extremely obese, but at 5'7" and my higest weight at 175lbs since having children, I just feel large. I also have Hypothroidism (on Synthroid). I tried Medifast (bad) and NutriSystem (3 months, lost 15 pds) but they discontinued my favorite foods and I got tired of the same 10 dishes. I gained it all back. I did the gym (weights and cardio, 1 hr a day X 4 days a week, for about 5 months). Exercise just makes me hungry, so I over eat and only lost like 2 inches and 10 pds. Went to a doctor and (after tests) got prescription for Phentermine. Only moderately curbs appetite for me and gives me dry mouth (but that helps me drink lots of water). Exactly 2 weeks so far and went from 170lbs to 165lbs. Not bad, we'll see if it lasts.

For Weight Loss: Lost 36 lbs in 60 days. Stopped the pill for 4 weeks and gained only 2 lbs up and down, so no real weight gain. When taking the pill, stick to a 5 meal a day plan to keep your metabolism kicking. I had no side effects other then minor sensitivity, funny feeling, while urinating. I slept about 6 hours a day and did not need coffee. Best of all my low T became normal after losing 15% body fat.

For Weight Loss: It's been 3 weeks and I'm down 9.4 pounds, this is my second time around, last year I lost more, but am still happy with the weight loss, but I do log my food intake daily, workout and walk 6-10 miles a week. When off this medication just continue to eat and workout the same, you will only gain back if you go back to your old eating. I had a family matter that threw me off, but I'm ready again and it's been a great help!

Adipex-P (phentermine) for Weight Loss: I am a 20 years old male, I was never involved in sports in high school. I started taking Adipex February of 2013, it is now June and I have lost 57 lbs! I have gotten off the medicine for about a month now and only take a pill every now and then as I start to lose my motivation but coming from 334 lbs and only being 5'10" it is amazing the difference you feel in your entire body. I am a full time college student and that makes it hard to focus on your health, but Adipex does it for me. I have had the dry mouth and it does tend to make me extremely irritable sometimes, but still does the job I have gone from a 48 in jeans to a 44 and some 42s fit.

Adipex-P (phentermine) for Weight Loss: About 8 years ago I was put on the antidepressant Lexapro, only to gain a massive amount of weight between Christmas and Easter. I was so shocked and it wasn't until one of my brutally honest acquaintances gave me the 'what the hell happened' look. My doctor moved me onto phentermine, and while it took a few weeks to kick in, once it did, it was great. But you have to work out also, and drink lots of water. Cravings for fast food and pizza do disappear. I felt awesome by the end of the summer and was at my lowest weight ever. Now here's the hard part: life after phentermine. This loses its effect rapidly. Use it wisely and you'll be successful.

Adipex-P (phentermine) for Weight Loss: I am 5'8 and was weighing in at 198. I asked my doctor for help and he prescriped Adipex and I can say it is the most amazing weight loss pill/tool available. I was ordered to take one pill a day but I started with (and still take) half a pill and for 3 days I didn't stop moving. The energy was amazing, I have absolutely no appetite, I only ate because I knew I had to. I only slept for about 2 hours at night during those first 3 days but after about a week of taking the pill, my sleeping became regular again. I have been on Adipex for a little over a month and have lost 18 lbs. I am still only taking half a pill and only taking it 3 days a week and my appetite has come back slowly but nothing like it was before. And no side effects!

For Weight Loss: I am a female with hypothyroidism, post menopause and over 50. I was at the heaviest in my life gaining over 60 lbs after being diagnosed with my thyroid disorder. I finally found a Dr. who would put me on Phentermine. I have been on it for a week short of 90 days and I've lost 32 lbs. There's nothing that in my 7 yrs fighting this hypothyroidism that allowed me to lose even 10 lbs. Not even cutting my daily caloric intake to less than 1200 calories a day. Which my Dr. wasn't at all happy about since she says 1400-1600 is the very least someone should eat. I am so very happy with the results. I wish of course I could have lost the entire 60lbs I gained when I got the slow thyroid issue. But I am nevertheless very pleased.
