epilepsy
"Depakote was the first epilepsy medication I ever took, and it did work in controlling my seizures; I never had a single one while on it. However, every single "lesser" side effect on the drugs.com description sheet happened to me. I became depressed, I gained weight, my body clock went totally haywire, and my periods, which were already irregular, became even more so. I attributed most of this to me just being in middle school (I was in 7th grade at the time), but most of it stopped after my doctor switched me to Lamictal a few months later. "
