Jerry,I don't think you caught the sarcasm in my original post. Night tremors isn't a medical term that goes along with your fears. Heck, I don't know that it is medical term/symptom period. It sounds like you have plain jane tremors. Which seems like 80% of the people on this forum have or have had. Including myself currently. So, I'm not seeing why you think this is so special.Stop stressing about this symptom, it is just creating a self fullfilling prophecy. There isn't a perfectly clear reason for everything. Everyone reacts differently to some degree. Just like if you and I both caught the same strain of flu.....we would both experience it differently. And if I asked my doctor why Jerry wasn't as ill as I was he wouldn't be able to pinpoint some specific reason. That is healthcare.
