Phentermine / topiramate
"This medication really made me eat less! It's not a conscious feeling of a decreased appetite, but you just don't feel "in the mood" to eat anything and nothing looks appetizing to you. I didn't realize it until I went on the scale and lost 8 pounds in the first week (on the lowest dose!). Started at 232 lbs 5'2" female- 24 years old. No other health complications besides overweight. 
HOWEVER, had to stop this med after 1 week because of horrible side effects. Dizziness- to the extent where I couldn't lift my head off the pillow in the morning (and through the day). Cognitive impairment- felt like I lost my brain. Can't think, can't come up with answers to any mathematical questions, can't concentrate. will try plain Phentermine."
