I am suffering with daily headache/ migraine with eye pain, nausea and temperature...plus all the usual symptoms that go with these DDs. I need a migraine prevention med (on Topamax but no change at all!) that will not cause weight gain... It's taken me 6.5 years to lose 40+lbs and I don't want to gain it all back...Thanks, Shelbo Ps...if something's helped you could you post the dose too? Thanks.
