Actually, for awhile, we were taking magnesium malate at night, until I ran out. Maybe he got worse after we ran out of that! Wow, I think you've hit upon something here.
I've read a lot of your posts, and I was planning on looking into that type of chromium. I did find some TMG, and he started that last night. He took some today with ice cream (one of the only thing he seems to be able to get down). I was even thinking of taking some myself, but don't know if I need it, except perhaps for depression, since I've run out of my Depression supplements. The Indian tea does help with that, though, thank goodness.
The gymnema sylvestre sounds like a great idea, too. Just finding the money will be the challenge.
