I just finished the Ultimate Cleanse for 8 days mainly for parasite cleansing. I felt good during this cleanse - lighter, but a little slower and I started getting sleepy thoughout the day. I feel this may be due to lack of sufficient iron. I would like to go back on this cleanse because I don't think 8 days was enough to eliminate any parasites, but I'm afraid I may be depriving myself of nutrients for energy. Unless this sleepiness is coming from the release of toxins...do you have any advice?
