I have a suggestion for something that has worked for me.

Since I started taking Vitamin B-12 (Methyl B-12 form) in larger amounts (1 to 3 mg per day) my diarrhea has been much less. In recent weeks when I increased to taking 3 mg of B-12 daily I had a regular bowel movement (sorry if this is gross). This is my first regular bowel movement in over a year! I felt like celebrating. I haven't had time to learn about B-12 to see if others have this effect from taking B-12. I have been keeping records and I am positive it is the B-12 that is helping me, since every day I take 3 mg I have a huge improvement and I don't have to plan my day around being near a toilet. Hooray!

Does anyone else notice this effect of vitamin B-12?

Oh, I originally tried the regular B-12 and it doesn't seem to be helpful, at least I didn't notice any improvements, it is specifically the sublingual METHYL B-12 that helps. I also see a huge improvement with my MG, I don't have as many of those days where I have to spend the day resting in bed.

Sorry you guys have diarrhea, it is not fun at all.
