"i love lithium!  was terrified to try it but no side effects. no weight gain as i have not been depressed and staring at the wall in a fetal position unable to move.  if i take it, it prevents mania (can tell when i forget) and depression.  drink more water - i try to drink 60 ounces a day and sweat more but no other side effects but i make sure to exercise usually 30 minutes a day. got bad news that should have thrown me into depression but since on lithium was able to talk normally, work out a solution, and function - thanks lithium."
