I recently had my first one. He said because of the medications I'm on he didn't know how much sedation i could have? and because I'm a smoker....well he didn't tell me i would have the most painful experience i have ever had. I cried through the whole thing...45 minutes i wanted to die on that table. I was frozen with fear...i couldn't talk i couldn't stop holding the side of the bed..thought i was going to break my fingers. I have panic attacks....and i let them know that. Is this normal? They did get 4 polyps out...but I don't think ill ever go through this again. Not once did he or the nurse in there ask me if i was ok...or stop and ask me if he wanted me to go on. If i could of i would of got out of that bed and ran. Has anyone else had this experience? medications for listing to me!!!
