... week. I am pain free have not had a migraine since a little head ache here and there but not painful at all. The only big thing I have with this drug is the weight gain and how I get so tired out easy. I am a active mother of 2 and I really need to change this but I'm afrain to switch to something else in fears of getting my migraines back. Is there something else my doctor can give to stop or treat those side effects?
