For Obesity: "My mom and Aunts went to the doctor and got these pills to lose weight, they all lost over 20 lbs. I weigh 227lbs, its been 4 days I've been taking Phentermine 37.5. Already lost 7lbs. Its great! I have lots of energy, I just always have a dry mouth, so I make detox water with lemon, mint and strawberry/cucumber and take it with me everywhere. Lets see if I can get to my goal 170lbs."

For Weight Loss: "It works! The best "diet pill" I have ever taken. I lost 40lbs in 3 months. Exercising is the key. You have to work out to see faster results. Side effects was headaches, only because I had no appetite. Constipation was an issue, but I took care of that by juicing veggies."

For Weight Loss: "My doctor wrote out this pill for me and I lost 9 pounds the first week. After taking the pill everyday for a week I had shortness of breath and the following Monday I had a huge panic attack that landed me in the ER... The pill does work but I can't handle shortness of breath!"

For Obesity: "I have been on phentermine for 3 months exact now. When I had started I was at 294 now I am down to 253. Thats 41lbs loss so far! Its has helped me a ton as well as counting my calories and a change of diet. I have only had the dry mouth and insomnia or having a hard time sleeping on it than usual but its tolerable. Other than no complaints what so ever. I am going to continue on my weight loss journey after this month without it. This was a great boost."

For Obesity: "I started taking a half of a pill today, I ate very little. The energy is great, the only thing I am noticing is that I am not able to sleep and I am tired, also a bit of dry mouth. My goal is to loose 45lbs so I can have a surgery that I desperately need. If I can take more weight off that would be fabulous."

For Obesity: "On the recommendation of a friend I started taking Phentermine 37.5. Went to the MD on 3/30/15. I didn't want to wait to start next day so I took my first pill in the car at noon on the 30th. Starting weight 284.5lbs. Literally hunger vanished, no cravings. Woke up next day, lost 1.5 lbs. Today, 4/1, I am down 3.2 lbs and haven't even taken my 3rd pill yet. I'm going to go to the gym today to see if that boosts the effect. I'm eating very lightly. Trying to stay below 1200 Cals a day. This pill really helps with not making poor decisions. The doctor recommended drinking gulps of water between each biteful of food. And to unlearn the bad habit of eating til I'm full or cleaning the plate. He recommended using a bread plate as my guide."

For Weight Loss: "So I have always struggled with my weight, I am either trying to loose weight or gaining it....there is never an steady weight for me. I feel like I can loose weight rather quickly if I give up 100% of my mindset on it, but the downside of that is I also gain just as quickly. Now that I am in my late 30's the extra weight is now effecting my health causing high blood pressure, high cholesterol, very low self esteem, and complete misery. I love clothes, but never even want to get dressed anymore because I am uncomfortable and can't wear what I love. I am to the point that the extra weight is changing my once outgoing, bubbly personality into a shy, quiet girl because I am uncomfortable in my skin. I hope this helps! I need it badly."

For Weight Loss: "Am in UK.... PHENTERMINE is not a national health prescription drug, so I have had to get mine through a slimming and diet clinic. Started at 24 St 9 lbs.... My doctor weighs and takes my blood pressure every 2 weeks.. After 2 weeks, lost 19 lbs, after 4 weeks lost another 7lbs, after 6 weeks lost another 9lbs. Lost 2.5 stone so far and feeling great apart from constipation. I am taking favored. I also get prescribed a water tablet and a multi vitamin. I pay £84 every 4 weeks which may seem a bit steep but I feel it's worth it...."

For Obesity: "Been on phentermine 1 month, today was 1 month appointment with my doctor. I have to go in every month and show any weight loss in order to get next month prescription. I lost 23 pounds in 1 month and am thrilled. Wasn't able to exercise due to pneumonia. But plan to in month 2. Side affects were little dry mouth that water cures, and if I don't take phentermine in the morning but later I have trouble getting to sleep. The medication after first couple of days really curbs appetite and I have to really make myself eat, and because I'm not hungry I am able to take my time and make good choices on what I eat!!! Also blood pressure is way down. Looking forward to month 2, and being able to feel healthier with more weight off!!"

For Weight Loss: "First day of Adipex.. My doctor wrote me a prescription for full dose but advised me to start with half of a pill due to anxiety I may have. Took the half pill this morning and boy do I feel the energy.. Hopefully I can stay on the half strength but I've been reading reviews that say that the effects wear off after a few days. I'm a nurse so I do like the extra energy.. My starting weight is 215..ultimate goal is 165..but for now getting under 200 would be great. Hopefully I can use this extra energy to go to the gym..I'll keep everyone updated. I love reading everyone's weight loss stories.. Good to know I'm not the only one who has weight loss as an issue. Best of luck to everyone.. And stay hydrate"

For Weight Loss: "Sorry . . Continued. . Started taking phentermine 37.5 and b12 shot once a week on 02/20/15. Started @ 225lbs and size 18. By 03/20/15 I am down to a 16 and weight is 213! My weight is coming off a little slower than most Lol but I've always had to work harder for my results, the reason I started this medication. But I am very pleased because I workout and eat healthy anyway so this is only an aid for me. W/o this med I would not have lost this much so soon. On my own with a strict diet and working out everyday I only lost 8 lbs in 6 weeks. Only side effect is I'm getting bumps on my face, shoulders, back, and chest. Sometimes can't sleep @ night, and occasionally dry mouth. I can deal with those! Feeling great! Will update in 30 days!!!!!!"

Adipex-P (phentermine) for Weight Loss: "So I have always been a big girl! I have 3 kids and with each pregnancy there was added weight that just carried over and you know how the story goes...I pushed myself and my wants and needs to the side and took care of everyone but myself. The more weight I put on the more depressed I got. I got to 280lbs!!!! My body was in constant pain and discomfort and I knew I had to stop and do do something about it. I started the pills last year and lost a total of 125lbs!!! Not just the pills but I started the gym, did zumba 3 times a week and started eating good. The pills aren't the magic fix. They just help you kind of like a kick start. Sure I had side effects!!!! But nothing that would out weight being close to 300lbs."

For Weight Loss: "I started 12 days ago. I have lost 14 lbs. I went from 184-170 so far. I need to get down to around 140-150 to be healthy again. I am 5'4. I love food, but I don't really even want it anymore...when I think it's a good time to eat I eat a few small pretzels. I have a little bit of dry mouth if I don't drink enough water, however I sleep well. I do have mood swings, which I have to remind myself are from the medication (so that I don't do anything dumb). I have noticed I am more emotional. Everything else is good though. I also enjoy the energy I have which last throughout the day."

For Weight Loss: "I'm 5'9" 227. I just started on 37.5 phen and here is my experience for the past 6 days. I've definitely had more energy. Too much in fact. Night time comes and I can't sleep. Last night I slept a full night finally. I take it first thing in am, too. Mine is the capsule formula. Dry mouth. Yup. Not bad. Drink your water. Little appetite. I have to remind myself to eat each day. Only time I feel hungry is shortly after I take the pill. I'm definitely making healthier choices in calories and I dont crave the junk at all which is awesome. I won't weigh myself until Fri. No doubt it's working though. I don't need to see the scale to know it's working. If I can sleep more, like last night moving fwd,I'd give it more than 7/10."

Adipex-P (phentermine) for Weight Loss: "This pill works! I do advise that you eat breakfast wait 30 mins and drink water throughout the day. If you don't get hungry eat something wholesome. My experience with headache, and mood swings was due to me not feeling hungry, yet my body still needed fuel. Listen to your body! I'm at a weight that I'm happy with. I do exercise its my therapy. One seventy three from 205! Also it helps with my blood pressure. Eating is so much easier. I can think about what I need to prepare versus just grabbing the first snack, not so good choice that would satisfy me. Know your body, breath don't over think, be happy. This is coming from me!It helped along with small positive changes. Peace!!"

For Obesity: "I started this med on 2/25/15 and my weight was 208 I'm 5'7" and I have high cholesterol I'm only 28 and I didn't want to start taking meds for cholesterol because the reason I have it is because I'm over weight so my doc told me about this med.

My side effects are dry mouth, but since I have been on this med I have stop drinking Dr pepper every day all day long to drink lots of water and tea I don't crave candy anymore and I watch my calories intake and I also exercise.

For Obesity: "Started four days ago. First day felt great! No appetite at all. The thought of food made me feel sick but I ate anyway so I didn't feel sick. Couldn't sleep at all. Day two was ok. Headache was pretty bad, upset stomach,jittery, slept 3 solid hours but that's it. Day three, headache, jittery, just felt weird but ate good and slept great. Day four, headache, extremely tired, sick feeling. I did have big bouts of energy about an hour after taking the pill. That's when I've been exercising. I have exercised all four days. No weight loss yet and feel like shit. I'm hoping this will all change after a few more days."

Adipex-P (phentermine) for Weight Loss: "I just started taking Adipex. I think so far it's helping me a ton, I'm on 1000 calorie diet plus Adipex. I'm working out every day, this is my 5th day and I already lost 6 pounds. Adipex seems to be helping me from over eating, it seems to be helping me curb my cravings. I have no craving for sweets of any kind, so far so good."

For Weight Loss: "Started 3/19. Day 3. Haven't weighed myself yet- waiting to hit the week mark. Haven't experienced dry mouth. But I am dealing with insomnia. Was up at 6am yesterday. Currently 3am the next day. Not tired at all. I do have energy though and a decreased appetite. So the medication is serving its purpose."

For Obesity: "Started phentermine 37.5 on Feb 3, 2015 at 272lbs. Currently at 258 lbs. It was really exciting at first because I lost about 8lbs in one week. Then I gained back 2lbs. (No reason, just did.) Since then I have lost 0 to 2lbs a week. I definitely feel that I am able to control my cravings and have some self control. I love that! What I did not love was the insomnia. It was so awful that my Dr. presribed Ambien. I am feeling much better with some solid sleep. I cannot express how much I hate using a drug to counteract a different drug. I want to continue with the phen, I feel as if it is helping. Hate that I have to pay a Dr. visit copay every month to get the prescription though. Doubles the cost of the phen."

For Weight Loss: "I started phentermine on 3-14-15. The dr's office weighed me at 189...I just stepped off my scale at 177.2! Not too bad for almost a full week on. I would say a lot may be water! Needless to say, I'm in love with this and cant wait to see where I'm at on my birthday 4-17."
