That's a pretty radical reaction. In all the years I've been doing 40 dayers and being around this forum I've never heard of it. If it continues you should go see a doctor, a naturpath or some healing arts professional that can better diagnose your condition . It sure sounds serious to me.
The question is how did >you< break the fast? How and for how many days? what have you been eating? What was your diet like before the fast? Did you do the MC "by the book? Did you cheat or added subracted from the protocol as written by Burroughs? Did you read the book, the SWF? Lax tea? Did you have any pre existing medical conditions?
