Lithium
"Lithium is the best medicine out there for Bi-Polar.  I have severe Bi-Polar with Rapid Cycling and have been on every medicine out there.  This is the only medicine that has worked.  I was always afraid to take it because of weight gain and the tests they have to run to check your lithium levels.  I'm glad I decided to give it a try.  I had the shaky hands side effect really bad I couldn't even write a sentence.   My Doctor then prescribed me propranolol and after one day of taking it I have no more tremors.  I take them 4 times a day. Make sure you eat before you take the Lithium.  Good luck."
