I've been taking Prozac for some time now and I think it really helps to keep my moods stable. I don't go into those terrible lows for weeks at a time. I still get into my moods sometimes, but it's at least manageable and doesn't get in the way of day to day activities. Tried to quit taking it, but I was absolutely miserable. I hate taking medication for anything, but I have to accept the fact that this is one that I need take. Reactions vary from person to person, so stay in close contact with your doctor. John
