obesity
"Day one on this medication....had taken phentermine before, gotten to goal weight, then thought I could maintain on my own, with exercise etc. Had some winter weight gain and getting started again. My doctor asked if I wanted to try something new. At first made me a little light headed, but better as the day went on. Problem is now, I have to be up in a couple of hours and can't go to sleep!..Hoping this goes away soon. Tomorrow will take it a little earlier in the day."
