I tried those meds two years ago and it all went bad. Really bad. I turned Buddhist for this same reason.
I promised my self not to take any med ever again. Meditation and retreats help me badly.
Hopefully haven't been critical in years, way better than meds. I promised my self that if I ever need them, I would rather gave up everything, become a 100% spiritual and become a Monk than take Lamictal, Valproic acid, or Lithium again.
