epilepsy
"I have used Depakote for the past 13 years now, 500 mg per day.  The only side effects were nausea and anxiety for the first day or two.  At that point, I was taking 1000 mg.  My neurologist pulled back the dosage to 750 mg and later 500 mg.  I've never had weight gain as a result of it and notice no ill effects with light drinking.  I did stop taking Depakote for about 6 months about 10 years ago and soon thereafter had a petit mal seizure.  I immediately went back on Depakote and haven't had an issue since.  Really couldn't be more satisfied with this medicine."
