Tom, I already Did stop!
The afternoon let-down (withdrawl?) was incredible, even though I was only taking a "baby" dose. The Amantadine that I began several weeks ago stopped addressing the fatigue, but was really good at suppressing my body aches...until I started the Dexedrine. Then the body aches were back as soon as the high wore off.
Its not hard to figure out why the stuff is so addictive -- cuz you feel so lousy when you Don't take it! And I wasn't getting a good night's sleep, which really made me kwanky! Grrrr!
