I've been on Lithium Carbonate for a year now I've had it in combination with all sorts. The thing is I was only prescribed the quick release version, and I take 500mg at night. Doesn't make a lot of sense really. So in the late afternoon when I take my 500mg it can pull myself together. So It definitely helps me out in the evening, but by the time I've woken up the next day its out of my system. So I've never actually tried lithium properly, and I have no idea why I'm not taking some in the morning.

Sometimes I have had it make me very anhedonic, but that was when I was just starting on it. But yeah it's a pretty useful drug, as someone said earlier Lithium is used to augment with Anti-depressants. I have read some of the reports and in one report 63% of patients stated that they had benefited from Lithium with an anti-depressant.
