I take Dilantin and high amounts of B12 to keep depression at bay. I can really feel the difference the B12 makes. I think the meds really deplete your system on B vitamins.

Keppra has that for a side effect on many people. I've been on it for awhile myself , but haven't had that problem with the side effects..

Yeah we were taking the B6 and we just had a serious outburst yesterday with my daughter. I was frightened she might hurt us or herself. Told the doctor we had to get her off this ASAP. She has been put on Topamax

I take keppra and I have bad mood swings ! Best thing that helps me is writing drawing or soothing music
