well, i definitely feel for you. i also experienced some of the discouragement you're dealing with right now when i finished my 20 day fast... my eczema returned and i also developed hay fever type symptoms. however, we need to look at the BIG picture!
it took years of unhealthful living for us to develop the skin issues we have... for me, i was raised by a mother who fed me nothing but macaroni & cheese and hotdogs. i barely ever had fruit or vegetables until i went away to university and started taking care of myself. i've learned that i just can't expect one fast to cure me of everything all in one go. this is a lifestyle commitment, and if we stick to it, and do a series of fasts with proper re-feeding in-between, i know we will see results and achieve a life free of skin issues!
