Janet, I used to get the muscle twitching too, but I don't know if it was because of the metals or the other problems I have or stress, so bad it would wake me up at night, and even make me feel wobbly. I'm worried about your eating yogurt. it is dairy based, thus highly inflammatory, and yogurt tends to have a lot of sugars in it, artificial or natural, both very bad.
I have been getting a lot better by strictly adhering to the diet, and I suspect that the detox my doctor put me on has me feeling ill (he said it would), but I still have a lot more energy. I tell you one thing that really helped me was to really clear stress out of my life wholesale. I got out of a toxic relationship, and started focusing on my job and my friends and my goals, instead of putting up with someone else's quirks and character flaws, de-selfing myself so that someone else coudl feel good about their twisted life. I really challenge you to clean your life and your diet, because I really do believe my metals toxicity pops out when I'm compromised psychologically.
I believe your body is screaming for attention, perhaps on behalf of your mind.
