For Weight Loss (Obesity/Overweight) "3/1/17 - Started taking 50 mg Topiramate at around 10 PM because it makes me drowsy and a calcium supplement to relieve the tingling in my hands and feet (called ProCal). 30 mg Phentermine capsules in the morning after breakfast (to prevent jitters, eat before taking Phentermine). Starting weight 189.5, age 26. 3/19/17 - weight 175. Pros - no exercise needed. No diet needed. Does curb your appetite away from sweet food. I eat fairly healthy anyways. Cons - tingling was unbearable until I started taking the calcium supplements. Increase fiber - possible constipation. Tips - drink a lot of water. I drank almost 3 liters of water before taking pills and while taking. Sometimes I flavor with Mio or lemon. Don't want kidney stones. Goal is to lose 50 lbs by September."

For Weight Loss (Obesity/Overweight) "I began taking phentermine and topiramate about three months ago and have lost a total of about 50 pounds. I have worked extremely hard on my diet and exercising as well. The only few negative effects I have gotten from the medications are small mood swings, constipation, and insomnia. Nothing too extreme. I am extremely glad my doctor recommended this for me because my weight and life were spiraling out of control."

For Weight Loss (Obesity/Overweight) "I’m a female teenager, and I first went on Topamax for my migraines (50 mg). My doctor also gave me phentermine (30 mg) to lose some weight because I was 203 pounds (5’6”). Not exactly the healthiest for a teenager. Experienced side effects from Topamax, mostly tingly feet and hands, diarrhea, and some headaches to begin. Side effects from phentermine were a lot worse, I had a fast heart rate, high blood pressure, dizziness, anemia, constipation, dry mouth, metallic taste, pulsatile tinnitus, and fever. Not all of these happen every day, but they come and go. The metallic taste in my mouth is all the time unless I drink water. The only good thing is I weigh 185 pounds. I’m not sure how long it took me to lose all of it, but I definitely lost 10 pounds in the first 14 days on phentermine. I didn’t exercise at all except I go to school and do a little gym class. I will start exercising and stop fasting so I can exercise. I’m willing to go through those side effects, though, to lose the weight."

Phentermine / topiramate for Weight Loss (Obesity/Overweight) "Took the 2-week starter dose. It made me feel lethargic and apathetic. I didn't feel like exercising. I would have been content to spend the day in a chair. I lost 4 pounds changing nothing. I think it was water weight. I then took the next dose for one week. I got terribly constipated with abdominal pain. I lost no weight on the increased dose. It did not change my appetite, and it took away my energy. I stopped taking the drug after 3 weeks total. 61-year-old woman, 5 feet 3 inches, 180 pounds."

For Weight Loss (Obesity/Overweight) "A little on myself, I am a 21-year-old with PCOS. I started the 14-day starter dose on 1/4/2015, today is the last day before I start the 7.5/43 dose. Since I've started, I've lost 5.5 pounds. I started at 186 and weighed this morning at 180.5. In the past two weeks, I have not done any exercise, and my eating has been rather sporadic because of a new job, week-long orientation, and having family visit for a week. I plan to kick things up this week, as I will have more time. In terms of side effects, I had some constipation, and at the start, it took some time to collect my thoughts, but after two days, that went away. One thing I did notice was that at the start, I had no appetite, but 5 days in, I was super hungry, but it went away."

For Weight Loss (Obesity/Overweight) "I have been on a roller coaster ride for ten years trying to lose weight. I'm trying Qsymia, it's my third day. My insurance did not cover it, so I paid $111 at Costco. So far, I have a dry mouth, a little headache, constipation, and a bit tired. Hope this works. Not serious symptoms, can deal with it."

For Weight Loss (Obesity/Overweight) "I tried the free sample and lost 10 lbs within the first week. After the 14 days, my dosage was increased, and I paid the $150.00 (after using my Qsymia discount) and lost nothing. It made me constipated, nothing helped. I increased my water intake, tried stool softeners, drank prune juice, and added more fiber to my diet. It wasn't until I stopped the pill that I was able to go (over a week). So I started using the pill every other day. I lost nothing after the 10 lbs from the first week. I will start Belviq next week, fingers crossed."

For Weight Loss (Obesity/Overweight) "I have been in peri-menopause and now menopause for 9 years. I did the average gain of 1-2 pounds per year. Started 186 lb in January. Lost 9 lb on my own, hit a plateau. Doc put me on Qsymia. I lost 14 pounds in 3 months and stopped, as my doctor didn't want me below 160 (5'8" tall, 53 years old). For my size, he said I looked good and didn't want me obsessing about weight. My goal was health and strength. I work out 30-40 minutes a day. Had all the usual side effects, hand tingling, dry mouth, constipation, which cleared when I stopped. I weigh myself weekly, and if I stay within 3 pounds of my goal, I don't worry. I still watch what I eat. I found it easy to make good choices while on medication, as I wasn't hungry and sweets tasted off."
