Thanks, guys!
Zuzu: Interesting thing about the palps. I have suffered from PVCs for ages but ever since I started taking magnesium they have become infrequent. That said, I would not welcome that problem again as I tend to get freaked out. Hmmm... I guess I can always try.
Moxie: Hang in. I work out (not quite as much as you) but I know how you feel about the struggle. The worst part for me is having my doctor berate me for not losing *more* weight! I don't know what part of the equation he doesn't understand!
Anyway, thanks again and good luck to all!
