Divalproex sodium
"Although reading the possible side effects can be scary, this medicine gave me my life back. I had a little hair loss, at doses above 1000mg, but it's been great in stabilizing my mood swings. If I go off of it, I have an episode within a month. I had no weight gain (actually lost weight I had gained from taking Seroquel previously). I take it with Wellbutrin SR and a little Abilify.  But the Depakote is by far the most effective. I've been on it for over 3 years."
