If you decide to try lithium, keep a close eye out for side-effects. When I was on it, it shut my colon down for months, caused such severe hand tremors that I almost flunked out of school when I had been an A student, and indirectly caused hypthyroidism that I'm still suffering from. Plus, it didn't help my mood, just turned me into a total zombie. Just another perspective............

BTW, there is a natural lithium called lithium orotate that I've done well on along with amino acids.
