I to have problems with claustrophobia/bipolar. I take Klonapin and that usually cures the panic attacks. I strolled into the operating room like I was going to a banquet bur when I was out and hooked up to all of the crap especially the leg pumping things I started to freak out. My wife and sister-in-law were right to witness all of this. SIster-in-law is a day surgery nurse from the unit over and was able to keep me calm till they got a shot in me. Of course the same thing happened later that night. I just kept the leg things off and I felt better.
Did I mention that my 7yr old daughter punched me right in the port tonight?
