bipolar disorde
"Have been taking it for 2 years. Stopped my seriously depressed moods 100%. My hyper moods as well, although did not have these as often. I was severely depressed and couldn't go to work, angry, and my mind was spinning all night.  This was going on for years.  I never realized it could have been a chemical imbalance until I "flipped" from giving up on life, to "everything is great!  What was I thinking!" Then back to giving up again within 3 hours.  Lamictal has made all of this stop.  It's wonderful to be "normal" again."
