Hey man, just wanted to let you know that the peaks and valleys that you describe at the beginning of you post can be helped. Tricyclic antidepressants do just that...they make the peaks not as high, and the valleys not as low. You still feel the things you're feeling...the extremes at both ends are just 'dampened' somewhat. They do help with what you're describing...just something for consideration. Good luck.
"Always go straight forward, and if you meet the devil, cut him in two and go between the pieces." - William Sturgis, clipper ship captain, 1830's.
