Re: the raw, vegan diet: are you taking B12 supplements, and if so, are you sure you're absorbing them properly? You can go for a while without B12, but after a few years a deficiency can cause extreme neurological symptoms (some of them are similar to the symptoms of MG). These can creep up on you gradually. If you start to get symptoms like you describe again, don't just assume it's the MG coming back--consider the possibility of a B12 deficiency as well. There are easy blood tests for that.

Vegans recognize that their diet doesn't provide B12, and that raw-food vegans are at special risk (because processed food marketed to vegans is often fortified with B12). This is not controversial. Please be careful. I think the gut destroys B12 before the body can use it, so you need a sub-lingual variety, and you should have blood tests to make sure you're absorbing it.
