Why did you stop Lithium Carbonate? If you were on a low dose and it was effective, but you stopped because of side effects, the orotate form might be helpful. It's the natural, gentler form of lithium compared to the carbonate. I've read a few studies that it can be helpful to boost mood, but it hasn't really been proven significantly effective in preventing mood episodes in those with bipolar.

Can't help ya with the medical advice over the phone though other than getting in touch with a doc.

(btw BPD is Borderline Personality Disorder, BiPolar disorder is either BP or BD combined with the appropriate specifier. Cyclothymia is the other subtype, but I think PennyNail meant bipolar, not borderline.)
