Well, I am still stuck in anorexia so I actually like that affect that topamax has if it has any affect at all ( haven't noticed specifically). It might just be counteracting any weight gaining meds I am on which is fine with me. I know that is bad but I feel that I am terrified of gaining any weight from meds. The topamax also works really well to keep most migraines at bay so I really need it. I started with a 10 year straight migraine and have gone down to 2 a month so I love the drug for that reason.
