Thanks, Mary, and I was just curious. When I first got sick, I took D-Ribose for over a year and it did absolutely nothing for me. But I have not tried whey or BCAA's. I was wondering if there is something that will give my muscles the final push so I open child proof bottles or hold a hairdryer (just as an example). I'd like to strengthen my diaphragm/breathing muscles further as well. So far (for me) only IVIG has been able to do this but it's like I am at the mid-way point and am hoping it can still do a lot more!
