Totally familiar with it! My left hand has been weak since diagnosed in 07.. not only weak, but it twitches. For example, when I am putting my contacts in I use that hand to hold the contact while I rinse it... My fore finger and thumb are the worst with the twitches and I usually throw each contact in the sink at least once... lol

It's very frustrating... I can't do anything with that hand anymore. The other night my fiance and I went out to eat and I tried to use my left hand to pick up something off of my plate to eat. It went flying across the table at him. He was like, "um, do you think you could NOT use that hand in public please?" hahaha.. it was pretty funny...
