Thankyou Dr. Bray. That has been most helpful. I have on occasions taken a very small amount of Valium but not keen to get dependent on same. I will however give the vitamins a try and it's interesting to know that valium can assist with the symptoms. It appears to be a long term problem, but I appear to be on the right track. Patience appears to be the answer while continueing with exercise etc. I now feel happier about using valium which you have recommended.
