I have been taking this medication for a week. The first day I did felt exhausted and slept my day away. So far I have managed to lose 4 pounds in seven days. The only side effect I have is dry mouth. I bought myself a refillable water bottle to carry with my at all times.

I started Jan 3 2014, the first week I lost 10 pounds! It's now 8.27.14 and I've lost 55 pounds total. I have been slacking and not working out but I love it. Dry mouth I still have it but makes you just want to drink water I have recommend tons of people! But I also take it at 5:00am or 4:40am and workout for half hour and then again at night for an hour or half hour gives me a lot of energy makes you sweat an not as hungry either. I would recommend it trust me they work.

Adipex-P (phentermine): I started Adipex on 8-18-14 & today is 8-25-14. I am down 8 pounds in a week. I hope this kind of weight loss continues but I'll have to wait & see. I did experience a little bit of nausea for the first few days but it wasn't too bad & dry mouth a little. So far I am pretty pleased.

I started taking phentermine August 15, 2014, weighed 203lbs, today 197 lbs. I've only drank water, had ONLY 3 sips of tea, calorie count varies between 600-2000. I have not cut out sweets/fried foods. I'm not cutting out all those that I enjoy eating, I'm cutting back. If I cut out everything, once I finish phentermine, the weight will come back rapidly when I start back eating regularly, this has been my experience when taking phentermine previously. I'm not going to eat just fruit, veggies, broil foods for the rest of my life, so why fool myself? I'm working out 6 days a week, in the morning and evening. This round will be much better, I'm more determined, my strategy has been thought out. I will post an update, BEST OF LUCK TO ALL!

I am 40 years old. I started taking Phentermine 37.5mg 6 weeks ago, and have been doing a 2000 calorie or less diet (because it is hard to eat that much, just not hungry). Just went to the doctor today, I have lost 23 lbs. I did experience a little insomnia the first couple of days but I take the pill at 5:30am before work and that seems to help. I sweat a lot for most part of the morning and have a lot of energy but dry mouth is definitely a side effect, but it helps with getting you to drink the amount of water you need to be drinking if you are not a water drinker like me. I do have a significant amount of weight to lose so hopefully the weight loss continues at this rate.

Update~ started taking phentermine on 7/18/2014 and as of today 8/14/2014 I'm down 15 lbs in less than a month. Dry mouth still happens but that's the only side effect for me still. My nutritionist has set my goal weight between 230 and 250 for my build and age...... So I only have 56 lbs left to go. More updates to come.

Started one week ago, no real change in appetite on 37.5 but did lose 4lbs. Cutting out as much sugar as possible and continuing exercising 3-4 days a week. Only side-effect is insomnia but started taking around 7:00am.

I came here to United States 2004, I was 140lbs height 5.8. 30 yrs old almost 9 yrs weight 176lbs I went to my doctor for a check up. Part of my history is diabetes and high blood pressure so I ask my doctor what else can I do other than diet. I start taking phentermine March of 2013 the very 1st day I took 37.5mg I feel like I can't stop working. I'm so focused, so fast I get done everything at work in no time I sweat a lot and had a dry mouth. I ate small portion of breakfast drink plenty of water no soda. No caffeine I ate yogurt for lunch and fruit in between for a week I lost nearly 7lbs. No workout or anything like that I keep taking it for a month, I lost 12lbs, my goal was 145 to 150 for 90 days taking it. I lost 25lbs after 90 days.

Hello. I'm a 28 year old female standing 5'3". I went to my doctor on 7/31/14 and was prescribed phentermine 37.5. At the office I weighed in at 275 lbs.! I started taking the medication on 8/1/14 (half a pill to see how it would effect my heart rate. I have hypertension). On 8/2/14 I weighed myself and the scale read 269.6. I only took half a pill that day, too. This morning, 8/3/14, I weighed in at 265 on the nose! I've been overweight since the age of three and remember being on diet pills at the age of nine. I've tried it alI. As an emotional eater who needed a miracle, all I can say is thank God.

I need to lose 30 lbs. I tried every thing, even the HCG diet. I was so hungry on that diet, it made me gain more weight. I tried phentermine 37.5 mg 7 days ago, and I am down 5 lbs. the first day I took it, I didn't eat all day long. It was weird and scary at the same time. I just wasn't hungry at all. My energy level was at the highest I ever felt. I had to keep moving. The next day, my body started getting use to the pill. I don't night snack any more. My last meal is around 7pm. If I start exercising I will probably lose more weight faster. side effects: thirsty all the time, but that helps me to get my 8 glasses of water intake. Sometimes I feel kind of emotional. that's about it.

I have had a lot of success with Phentermine 37.5mg The first time was 3 years ago when I lost 30 pounds in 2 months. I am 5'3 and weighed 180 and after 2 months on Phentermine I was at 150. This time I am 45 years old and started out at 165 and after 1 month weigh 150 so I have lost 15 pounds which is the same rate I lost the weight before. I do take the pill early in the morning around 6am if I do not I do experience insomnia. I get full very fast after only taking a few bites of something I am done or I become nauseous. Phentermine has also caused me to have a dry mouth you just have to drink a lot of water which is good for you anyway. All and all my experience has been very good. It does really work. Just have a physical first

I am 19 years old, 5'3. The very first time I took this was back in January of this year. Took the 30mg. My start weight was 180lbs, that's the highest I've ever been. I took it almost everyday, worked out regularly, but I didn't eat so well. Somehow I managed to go down to 170lbs by the time I finished the 30 pills in the bottle. I took it in the month of March and went down to 165lbs and then I stopped taking it for a while. I just went back on it, doing the 37.5mg now. Start date 07/22/14 weighing in at 165lbs and today I am 161lbs.

This medicine has been so helpful for me. I am 44 years old and have struggled with my weight my whole life but was able to maintain my weight until I had my fourth child via cesarean section. I started on phentermine on 07/15/2014 weighing in at 250 pounds and as of today, 07/25/2014, I have lost 8.2 pounds. I am also counting calories doing 1200 per day.

I am 39 years old and I have been trying to flatten my stomach ever since I had my last child 15 years ago. I will admit I do love food! I heard about using Phentermine from a friend of mine, and I thought to myself, wow this might actually be what I am looking for! So I made a doctors appointment and she gave me a script for this on June 6th 2014 and I got it filled and started right away, I was told to start out using only half, so I did and didn't feel that it was working using only half so the next day I started taking 1 whole pill. I can say that it was all good, and to date I have not had any side effects. When I started using this medication I weighed a wooping 186!! and today 7/23/14 I am at 168, & want to be about 140.

I was signed up to have the gastric sleeve procedure done but cancelled a few days prior wanting to try again to lose the weight on my own. I was 245 pounds March 28th and am 5'5. I started Phentermine shortly after that. I am currently 209lbs and it is July 22nd. Very happy with the results. Glad I didn't have the operation even if I would be skinner now the risks were just too scary for me to go through with it. I would love to get down to 160lbs! I am going to keep chugging along.

Adipex-P (phentermine): I started off on the highest mg which is 37.5 and it has worked very well for me. In my first month I had lost 26lbs and in 6 months, I lost a total of 90lbs. I DID NOT EAT HEALTHY NOR DID I EXERCISE. I took a break from it a couple of months back because it's not safe to take it for an extended period of time due to the fact that it takes a toll on your liver. I just got back on it again yesterday. It will cause you to have DRY MOUTH, CONSTIPATION, URGES TO DRINK LOTS OF WATER, ENERGY, ABILITY TO STAY FOCUSED, INSOMNIA, FAST HEART RATE, MOOD SWINGS, NAUSEA AND EASES BODY PAIN. I have a heart murmur and panic attacks so after taking this medication, I notice it gets harder for me to breath as the day goes by.

I'm a 24 year old single mother, and diet and exercise was never in my vocabulary. However, I am the heaviest I have ever been. (weighed less when I was 9 months pregnant). I have taken phentermine 37.5mg once before and I had no idea what to expect. I know that this is not a magic pill, but more of a booster. I've lost 25 pounds within a month, worked out, ate less and consumed more water and cut out sodas and fast food. Was able to wear smaller clothes and the confidence came back. I'm back on it again starting yesterday 7/17/14, and hope I get the same results as last time. My side effects were dry mouth, feeling a little more irritated, heart was going fast, the feeling to constantly move. Smoked constantly. Good luck everyone

Adipex-P (phentermine): I started taking Adipex on July 15, and I must say I have definitely seen a difference in my eating habits and it's only been 3 days! Amazing! I was 127lbs in 2012 and somewhere along the line I lost the will to work out and stay fit. Needless to say I gained about 35lbs since then so I am giving Adipex a try and it's doing wonders for my appetite! I experienced dry mouth the first day and that's the only side affect I have had. I eat a yogurt for lunch and dinner is 2 turkey sandwiches on wheat bread, and I drink 2-3 bottles of water a day. Eating right and exercise are key to helping drop weight quicker! Once you stop taking the pill you must maintain good eating habits along with exercise or the weight will come back plus more!

I can really say that I was nervous starting this pill because I read the reviews and didn't want to experience the side effects. I just started this pill on Tuesday, 7/8/14 and it has now been exactly one week and one day. I started weighing 188.6 and as of today, Wednesday, 7/16/14 I weighed in at 180.4. So that makes a total of 8.2 pounds lost in just one week and and day. I normally work out but I didn't work out for this entire week purposely just to see how much weight I would lose without my daily exercise. I did however maintain my healthy meal plan and I drink 1/2 to 1 gallon of water daily. I am 25 years old and 5'10. I haven't experienced any side effects (knocks on wood so I wont begin to experience them, best wishes to all!

In my last post, I had lost 8lb in 2.5 weeks. Starting weight was 181lbs, I currently weigh 168. I have been on Phentermine for about 6 weeks. I have had a busy summer, in which I would usually gain weight however, I have continued to lose even though my busy schedule makes it hard to work out every day. Currently down 13 lbs! I will begin to increase my workout schedule as I am not as busy anymore. Hoping to lose another 10-15lbs within the next 8 weeks (maybe more!).

Adipex-P (phentermine): I have been on this medicine for nearly one week. I have lost 8lbs since starting this medicine. I take half a dose on a empty stomach and then drink protein drinks both for breakfast and lunch. Then eat a light supper and been eating about 1100 calories or less a day. I go to the gym about 3 to 4 time a week. I have noticed every day a change in my weight. I haven't had any side effects my blood pressure been running great. I don't experience any nausea or vomiting with this medicine while working out. I am planning taking this medicine for 1 month and then taking rest and start it again.

I was prescribed Phentermine for weight loss as I was about 70 lbs overweight. I'd been struggling for 18 yrs with depression and anxiety from a traumatic event and even though the doctors prescribed antidepressants and anti anxiety meds, I still felt lost and sometimes suicidal. Within about 20 minutes after taking my first phentermine pill, I felt absolutely "normal" again. Imagine 18 yrs of struggling, not being able to focus, falling behind at work and at home, losing track of my thoughts and not able to hold a decent conversation then a weight loss medication gave me back my life. As for the weight loss, I changed my eating habits, stopped drinking soda and lost 18 lbs within three months.

My experience was successful! I started the pill on 03-26-14 at which time I was 287 lbs, by 04-30-14, I dropped down to 276 lbs. I must say it really suppresses the appetite and I recommend that you eat at least breakfast daily to avoid getting headaches and feeling nausea. Altough, I did have those side effects, I do recommend eating something again as stated preferably breakfast. The last time I weighed myself I wore 266, however, because I am no longer eating healthy and taking the pill when I remember to take one I notice I have gained some of the weight back as my pcp indicated I would. All in all Phentermine is great if you are going to adjust to permenant lifestyle changes / eating behaviors.
