I take (have taken for years) Depakote ER (750 mg/daily). I take this for, I believe, 2 reasons. 1) For migraine prevention. and 2) I have (at the present time) a Vaproic Acid level of FOUR (4) mcg/mL! However, I am greatly concerned about weight gain, have recently been experiencing nausea with and without vomiting, dizziness and fatigue. Is there an alternative medication that would work (even better) for me? Thank you for your help!
