Lithium
"I've had a severe manic episode and was put on antipsychotics which helped calming me down but I was still a bit manic. When put on lithium I felt a lot better because mania ceased. The difference between antipsychotics and litihium for me was like if antipsychotics stepped on the brake and lithium lifted the gas pedal. 



The only, but still significant, side effect I've had is less short term memory.



Lithium stabilize my mood, less anxiety and stress (less diarrhea, less neck pain, more relaxed), better sleep not just because mania stopped but also because overall well being



I'm very satisfied with lithium as a mood stabilizer"
