Dawn, I haven't done any saunas, but the info that I have read states that the sauna depletes minerals and that they must be replaced. I know that I am often magnesium deficient and that when I am, I go numb in my extremities, am shakey all over, dizzy, faint and have heart palpitatioins. Get some minerals into you fast - esp magnesium! Juice some vegetables if you have a juicer and drink lots of juice today, tomorrow - see if you don't feel much better! <img src="/ubbthreads/images/graemlins/smile.gif" alt="" />
