I've only done 11 flushes - so I'm no expert like a lot of people on the forum. But since you haven't got anyone to anwer you - I thought I would give it a shot. I know that there have been a few flushes that made me feel tired afterwards, and when I did the next flush I felt great. Many might disagree with me, but if you feel up to it, my opinion whould be go ahead and flush again. I have done 2 flushes that were 1 week apart, and it was ok. Have you looked into other causes for your fatique ( food allergy , gluten allergy, etc.)? It can be very fustrating - keep on searching for the answers. Good luck!
