[B I firstly apologise for being persistent with my posts in the lat day- I am desperate to try and stop these rolling migraines again- and it is disressing to also have a return of my other hypothyroid ymptoms, which initiall seemed to be getting better. I am at week 6 in the Fredd protocol and have had a significant return of previous hypothyroid symptoms- including muscle aches and pains, numb feet and migraines. These all seemed to be reasonably improved for weeks 2, 3 and 4 on the protocol. Then at week 4 I increased methyl folate from 800 to 1200mg a day and have been having increasing problems with symptoms since then. Dan inculded a literature post that seemed to indicate that a deficiency in b12 could cause folate to exaccerbate symptoms. Perhaps this is what is happening- has anyone else experienced this or got any views on this? In the absence of any better advice, I think I will go back to the old dose of 800 of folate and stay on the reently increased dose of 1000mcg of mb12 and try and see if I can improve again.
