bipolar disorde
"A few weeks ago decided to go off lithium because I felt "fine".....bad decision.  I went right into a severe manic state.  Paranoid, delusional, severe anger.  Back on lithium and all is well again.  Only side effects for me are extreme thirst/dry mouth and sore joints.  I take 450 mg ER twice a day.  Lithium allows me to go to work every day, pay my bills and enjoy life in general.  Highly recommend."
