I just started this diet but am wondering if anyone was put on this combination. My doctor said the Topamax will help with the headachs as well as sleeplessness that comes with this drug. I am a little scared of the whole thing but want to loose weight so bad. I have been on the Phen for a week and have really experiences apitite loss. but my energy level is a little low. I also seem to be a little sensative to light but besides that so far so good.
