For Weight Loss (Obesity/Overweight) "Had lost 80 pounds from lap band and stalled with 30 lbs to go. Dr. recommended phentermine to get over the set point, and I tried it. In 3 weeks, I've only lost 5 pounds. The constipation and dry mouth are huge, but I haven't experienced any other side effects. But then again, I haven't experienced any primary effects either. Seems to me like if you're going to risk a controlled addictive substance, the reward should be more than 5 pounds."

Phentermine for Weight Loss (Obesity/Overweight) "I'm a 33-year-old male who was 198 lbs. at 5' 5'. I have been taking Adipex-P 37.5 since June 16, 2011. Five weeks later, I have lost 15 lbs. (183 lbs), that's about 3 lbs. per week. I haven't changed my meals that much, but I wasn't a big eater before. I've just cut way down on sodas and drink mostly water. Dry mouth and constipation are the only side effects I've experienced, but that is where the high amount of water intake helps. One thing I learned after starting this is that drinking ice-cold water helps you lose weight because your body burns calories trying to bring that water intake up to body temperature. My goal was to get down to 165 lbs., so after 5 weeks, I'm halfway there."

Phentermine for Weight Loss (Obesity/Overweight) "I am 5 ft and 160 lb. I'm a short, round pear. I started Adipex in September (I think). I have only lost 10 lbs. I put on a lot of weight when I started taking my thyroid medicine. I have changed up my eating habits some and have been trying to go to the gym 3 days a week and go walking with my dog on the weekends. At first, when I took it, I had light headaches, and I felt like I lost all my energy by mid-afternoon and was a little constipated. Now I feel fine. Dry mouth and still light constipation. I just thought it would work a little better for me. I am trying to eat better, it can be so hard when I have to make dinner for my hubby and make me something else and being around the holidays. I am hoping to lose 20 more pounds."

For Weight Loss (Obesity/Overweight) "I requested this medicine from my doctor after having a tumor in my knee for 4 years, restricting my mobility and causing me to gain a ton of weight. I started on 9/2 and took my 30-day supply. I stopped for about 2 weeks after my supply ran out so that I could use the restroom properly (without constipation). Went to the doctor last week on 10/21, I'm down 15 pounds already! Got another script, ready to keep this journey going!"

For Weight Loss (Obesity/Overweight) "Second month update... I lost 8 lbs this month. I was hoping for more, but I have not been able to get up to go to the gym due to insomnia. I am a morning workout person (before work). I have no problem falling asleep but usually wake up after only 3 hrs, and then I cannot fall back asleep until right before it is time to get up. As exhausted as I am, my next dose of phentermine gets me through the day, but it has become a vicious cycle. Today I skipped phentermine for the first time as my body needs sleep, and I plan to resume tomorrow. Another side effect I have experienced is constipation, but a stool softener took care of that for me. Overall, phentermine has been very helpful. I have been alternating my calorie consumption."

For Weight Loss (Obesity/Overweight) "I started taking this medicine in 10/2008 (1 pill a day in the beginning/2 pills a day in the end). I weighed 240 lbs (male) and had been stuck here for 2 months following a 20 lb weight loss. This medicine saved my life. I took it from 10/2008 until 03/2009. I now weigh 182 lbs. I learned portion control and the right way to eat. The medicine helped give me energy, which helped me learn how to exercise. I had a few side effects in the beginning. I was constipated for the first month or so. I had to pee a lot. I suffered from dry mouth and had a hard time sleeping for the first couple of weeks. These symptoms all went away after about 3 or 4 weeks. I stuck with it and am glad I did. Stopping the pills was no problem for me."

For Weight Loss (Obesity/Overweight) "I'm a 28-year-old woman who has been struggling to lose weight for the past 10 years. I started the phentermine 37.5 mg in January of this year. However, I started having slight chest pain and high blood pressure. I was taken off of it, and I was put on the 15 mg. That seemed to work for the time being, but as the days went on, I noticed the appetite came back faster. So when I went back and saw my doctor on February 1st, I was put on the 30 mg, which is what I'm on now. Let's just say this: I was 232 pounds last fall, and I'm about to cross into the 190s now. The 30 mg is working well for me, I have no cardiac problems, my appetite is completely gone, and I have no desire to eat any of the terrible things I was used to eating before. The only side effects that I experience daily are dry mouth and some slight constipation. I strongly recommend it; however, talk with your doctor and be mentally prepared to make the changes at home because this pill won't solve everything in the end!"

For Weight Loss (Obesity/Overweight) "Male, age 75. SW 244, CW 232, GW 179. Started phentermine 30 mg twice per day on Sept 14. Have lost 12 lbs in 19 days. This medication is really great for appetite control. Sometimes I have to plan to eat. Calorie intake has been controlled to between 800 and 1,200 calories per day. I have found that drinking enough water is a challenge. Have managed only about 32 oz per day. Side effect is mostly constipation, which is easily managed with more fiber. Sleep is a bit disturbed. Although I feel rested during the day, I wake up several times a night, which has not been my habit. The downside issues are more than offset by the benefits of taking the medication."

For Weight Loss (Obesity/Overweight) "This medicine didn't do a thing for me. I started at 234, I'm still 234. I ate right, drank lots of water, and even tried intermittent fasting. This pill made me constipated and gave me dry mouth. On to the next."

For Weight Loss (Obesity/Overweight) "I got put on phentermine 37.5 in March of 2010, and my weight when I started taking it was 242. Now, in November 2010, my weight is 162.7 lbs, and from a size 18 to a 10/12, 2X to a large. I've always struggled with my weight, have tried every diet; nothing worked like this does. At my all-time highest weight, which was 350 lbs, size 4X, and 28 in jeans due to depression. So now, in my 30s, I'm looking better than I have ever looked my whole life. Phentermine has done wonderful miracles for me. A few side effects, minor ones though, but they were/are at times: headaches (minor) and constipation. Hope this eases those who are terrified and 'assume' phentermine will do all these bad things we heard in the past."

For Weight Loss (Obesity/Overweight) "I am 41 years old and have been taking phentermine from September 2, 2008, to December 20, 2008. I have lost 35 pounds. It has been a huge blessing in my life. I went from size 20 pants and 2X or 3X tops to size 10 pants and from large to medium tops. It is awesome. It has been a great experience, but be sure to see a doctor before taking this medication. The side effects I experienced were dry mouth (I chewed sugar-free gum all the time and drank lots of water) and constipation. It seems to get better after being on the pill for a while. Energy (treadmill 5 to 6 times a week, and get this - I love it). I'm taking a three-week break right now. I'll let you know how it goes. Good luck."

For Weight Loss (Obesity/Overweight) "Two weeks now on phentermine, and I've dropped 12 lbs. I've also been meal prepping and limiting caloric intake to about 1,000 calories a day. Lots of protein, moderate carbs, and under 20 gm fat a day. I'm not hungry, and I have enough energy to get through the day. Started at 253 lbs, and goal is 170-150. The first day was rough... really bad headache and jittery. But since then, I've been fine. Lots of water, as well as soluble fiber, to keep the constipation at bay. Yesterday, I put on pants I haven't worn in two years. I miss sugar, but I'm not craving it. It's also fun to be cooking again! My peers see my meal prep and think I've gone out for takeout. This med is the kickstart and motivation I need to keep going. I'm super excited to see what I can keep doing!!"

This is not a mentioned side effect, but I'll continue this little pill forever if I can for that one reason! The chronic constipation is horrible, I have to take Ducolax a lot."

For Weight Loss (Obesity/Overweight) "I've taken this pill on and off for a year. I too had dry mouth and restlessness along with aggressiveness, but I ran across a solution to rid myself of all of the above. I take Calm, which is magnesium and is all-natural. It is good for all of the above symptoms, including constipation. I use the powder form, and it states you can use as much as you like to get the desired results."

I started Phentermine 30 mg on 6/10 and just had my 2-week follow-up today, and I have lost 8 pounds so far, it was so exciting! I am on a 25 g of fat and 30 g of sugar per day diet, it's pretty easy! Normal symptoms: dry mouth, some constipation, insomnia the first few days, but nothing that I can't handle. Will update! (:"

For Weight Loss (Obesity/Overweight) "If you take this medication and do a complete diet change and add exercise, it makes a lot of difference. The first month, I only used the pills and changed my diet. My killers were the cheesecakes, apple pies, and lots of bread. I completely cut all of these out of my diet. About a month ago, I joined the YMCA, and now it has become an obsession. I got all the symptoms listed above, but because I take mine in the morning, I do not get the insomnia. For the constipation, I drink lots of water. I add Miralax to a pitcher of water and only drink that and drink green tea. This has helped me combat the constipation. I started mine on 1/11, and I have lost 30 lbs and down 2 dress sizes. Now I am on 1/2 tablet when needed. I call it my brain programmer."

For Weight Loss (Obesity/Overweight) "Started taking this 4 years ago. Lost 20 lbs. It works, but if you take it too long, you have terrible side effects. Severe dry mouth, bad breath, wired, can't focus, constipation. I mentioned to the doctor the side effects, and he said he's never had anyone complain about any negative side effects. I also asked if I should only take the medication for a certain period of time, and he said no. I guess he got his money, so he didn't care. I just went off it and have gained about 8 lbs back, but that's because you fall hard. You are tired all the time. Like I said, it works, but I think I will try eating healthy and exercising."

The only thing is I have bad constipation, but that can be fixed. I do exercise 3x a week, and I do eat healthy but treat myself once in a while. I recommend it to anyone who wants to lose weight and keep it off."

For Weight Loss (Obesity/Overweight) "Phentermine was just what I needed to help me lose the weight I needed to lose. I have a high family risk of diabetes, high cholesterol, and stroke, so when my blood sugar showed that I was pre-diabetic at 168 lbs., my doctor put me on a 1200-1500 calorie diet and phentermine. I've always exercised three times a week. I lost 20 lbs. in three months and lost another 10 lbs. in the last year. At first, I experienced side effects of dry mouth, trouble sleeping, and constipation, but that subsided over time. I am still taking the medication, going in for monthly weight and blood pressure checks, but lately, I have been feeling like it is losing its effectiveness. I'm a little concerned about its addictive qualities and plan to ask my doctor about it."

For Weight Loss (Obesity/Overweight) "I am 35, 248 lbs and am taking phentermine (generic Adipex). I have taken it previously. I am familiar with how it would affect me. I am using it in conjunction with a healthy eating plan and exercise. I take 1 pill every other day 1st thing in the morning. I know from previous experience taking it every day, it makes it very hard for me to sleep at night and also makes me constipated, so I have increased my fiber and water intake. Without the medication, it was extremely hard for me to get started eating better and limiting my calorie intake, plus start exercising again. It really is a great kickstart to give you energy and help keep you on track when going through a lifestyle change like you have to do to lose the weight when you are obese."

For Weight Loss (Obesity/Overweight) "I'm a 66-yr-old female who started phentermine in August. I lost 12 lbs the first month, 6 lbs the next month, then 4 lbs, and this month only 1 lb! Just read all the blogs, and I'm going to stop the medicine for 3-4 days, then start again. At my last Dr. visit, he upped my dosage to 2 tabs/day. According to the blogs, I'm taking the tab at the right times of the day and in the right way. I have an extremely active job and am on my feet 5-1/2 hr non-stop 5 days/week; however, I'm getting ready to start traveling with my husband in our RV, so I plan to start exercising by joining Curves/walking. I'm thrilled with the way my appetite has decreased, don't think so much about food, and only eat fruits and veggies with a regular meal at night. Constipation is awful."

Then, suddenly, my energy disappeared, and I started feeling funny and getting strange headaches. After almost passing out, I rushed to the doctor, and my blood pressure was extremely high along with my heart rate! This is not a drug to play around with!"

For Weight Loss (Obesity/Overweight) "Am in the 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 7 lbs, after 6 weeks, lost another 9 lbs. 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 multivitamin. I pay £84 every 4 weeks, which may seem a bit steep, but I feel it's worth it."

For Weight Loss (Obesity/Overweight) "I started taking Phentermine last summer to increase my energy and as a nice side effect to lose weight. I was walking (fast) 3 miles every day. I was on oral diabetes medication. Through the exercise, I lowered my cholesterol 41 points, got off the diabetes medicines, and lost 9 lbs. Phentermine did decrease my appetite, but didn't help me lose weight. I ate EXTREMELY healthy, watching carbs, calories, etc. The side effects were horrible constipation, I would drink HUGE amounts of water every day and still had extreme dry mouth and skin. Phentermine did increase my energy, sometimes feeling very jittery, especially at first, finding myself wired and only sleeping 3-4 hours a night. NOT WORTH THE SIDE EFFECTS FOR ME."
