Blue, I don't think either you or I COULD OD, since we've built up a tolerance, and because we use it just for PAIN. I'm just like my Dad, and it takes about 4 times as much medication to even put me to sleep, and THEN I wake up DURING SURGERY!! I woke up on the table when they were operating on my spine TWICE -- and they'd given me curare so I couldn't move -- and I was of course face-down, so they couldn't see my eyes were wide open. The anesthesiologist evidently wasn't paying attention -- I heard them all talking about what they did that weekend , I laughing & joking, yadayadayada, and I kept trying & trying to MOVE something -- this went on for I don't know HOW long, until I finally managed to move my little finger -- then all HE@# broke loose, and the anesthesiologist hollered "SHE'S AWAKE" -- and Ii heard things banging, & people moving all over the place, LOL -- he finally gave me more happy stuff & put me back to sleep -- but if that wasn't scary! That happened for the 2nd spine surgery, even after i'd told them it happened the first time!

Then I had oral surgery and had to be put out -- and darn near killed the surgeon when I awoke during the surgery -- I was reacting to the anesthesia, and got violent! LOL He put me back out, but when it was over, he said he gave me enough for 4 BIG guys.

So see? We need more juice than most people. I'm sure you're just like that from the sounds of it. Have you have woke up during surgery? I curious!!!
