I hope you're feeling better soon. I know all about being sick - yuk.
I agree with everyone else, wait until you're feeling better (no more aches and pains) before you start exercising again, you don't want to set yourself back health wise.
Lots of water and vitamins will help.
I started taking a daily multivitamin and 1000mg of vitamin C about a month and a half ago, and anything that I have been catching has been going away as fast as it comes
Of course I do smoke, so it doesn't help matters much - but that's another goal I'll work on when I'm ready
