That's a good idea you have to go to the facility and send a message to your doctor. If they can't get you an answer today try to get them to move up your appointment. Four months is nuts to me. Good luck with that and be diplomatic but don't let them give you the run around. Finally, you could try the things suggested here...Benadryl, Tylenol pm or NyQuil. Good luck and best wishes in getting everything straightened out. Sleep deprivation can cause serious problems.
