I've been posting here for about 6 weeks. Once I started taking my focus off the twitching, I also noticed it much less.
I've also had concerns with perceived/clinical weakness, but I'm as strong, if not stronger, than I was when this started. I'm now doing 15 pushups with my 35 pound 3 1/2 year old son on my back. He enjoys it, but my wife doesn't and thinks I'm nuts.
I went to a Steelers game a week ago and walked from downtown to the stadium, about 1 mile or so walk each way. When I got home, my legs were hurting so badly that I would have sworn I have the bad disease. The next day they felt fine and no weakness. I think once the weakness hits, it hits hard and never gets better.
