I am also on topamax and have always had problem with my weight...not to much but to little. The first 3 months were hard and I didn't eat much and lost quite a bit, but it has tapered off quite a bit now and my appitite is beginning to come back slowly. The average person....average weight and height may only see a few lbs lost the first few months and then start to go back to the way they were. If you really want to lose weight in a healthy way you should eat more small meals throughout the day and exercise, unfortunately the side effects causes you to not want to eat and your metabolism with slow down to a slugs pace by the 3rd month.   I hope this helps with your question.   L Rodriguez
