I am 18 months off but this one problem bugs me a lot--fasciculations. IF you read up on it, it is a symptom of major diseases like ALS and other nervous system diseases. It can also be benign. Here is a video that shows what I have. It is mainly in my calves and occurs daily. It started about 7 months ago. So, could this be related to withdrawal syndrome, or should I get checked out? http://www.youtube.com/watch?v=f5t9RbOmlyM
