Phentermine
"I started taking phentermine 37.5 today. I have read a lot of comments here, but I don't think I have read of anyone else taking topiramine with the phen. 
This is my first time on either drug and am pretty impressed so far. I have had little to no appetite today and have had to force myself to eat. I am diabetic, so I am no stranger to carrying a bottle of water. Any suggestions to help me get the most out of phen would be greatly appreciated."
