Regular treadmill and water rower use but not excessive. Nothing since the MG kicked in - on Doc's advice.
It’s hard to imagine a doctor recommended no exercise.
I would try going to 100% wheat free for a month.
I’m a bit of wheat and gluten free advocte these days. Because it changed my life. I could barely walk, my joints hurt so bad, I had a big fat stomach that blew up like a balloon, And acid indigestion so bad it would make me unable to sleep.
Everything went away when I stopped eating wheat.
But try it for a month and see if it works for you. But you have to be religious about it... One misstep resets the clock and you need to start over.
Also take a ton of vitamin D for a week
