I think I can get betaine anhydrous today without having to order TMG from A***zon. Cursory reading mentioned taking at night could disrupt sleep.Yes thats the same thing.
So I will focus on foods rather than supplements for my Bs. I am really encouraged by your comment on this perhaps being at the root of my problem. Could it be as simple as synthetic vitamins not being the best, or not needing nearly as much as I (didn't realize) was getting from food already? I do eat well- lots of good-quality animal protein. raw dairy, pastured eggs.
You are a godsend. I am truly grateful to you.
