I am an 5 foot 7.5 inches 158 pound eighteen year old african american female. Ever since November of 2011 my muscles have been twitching CONSTANTLY. I drink water, eat bananas, and I eat cheese and nothing is working. I am on concerta and zoloft but I have been on that since late 2010. I just want the muscle spasms to stop. They don't hurt their just annoying. I just want it too stop. They make me really depressed and they keep me awake at night.
