Whenver I try a 5 day water only fast, I get terrible headaches within 24 hours and have to pull out as it gets more and more instense. Then it takes another 12-24 hours to recover from it even after eating. I tended to think it was flushing everything out including nutrients.

So if you carry on with the water only fast past the headaches do they go away?

Many years ago I tried a 7 day fast (long before I was diagnosed with AS or had any symptoms) out of curiosity but I used watered down orange juice. I still got headaches, but not as bad and they eventually disappeared.

Regards
Darren
