Thanks everyone. A friend tried to calm me down, but my imagination just gets carried away. Logically I know it more than likely is withdrawals but then a voice says 'well alcoholics can get MS too'.
I think the mental torture and increased anxiety is one of the worst aspects of this madness. Throw in a bit of psychosomatic aches and pains to boot and I'm jumping out of my skin altogether.
I guess if I still have these symptoms in a week then a trip to a dr wouldn't be excessive. Thanks guys.
