I remember my extraction. It was actually life threatning, or somthing like that...
It seems that the top two had giant roots that left a hole in my sinus cavity, and it would take a LOT of anesthisia to put me(360+lbs at that point) to sleep. During that, it was possible for blood/snot/spit to drain up into those holes, drain down my esophogus, and into my lungs, strangling me while I was... well, while I was. I really can't describe it's sensations...
I was on hallusanagenic painpills for about a two weeks, with cotton completly filling my mouth(and getting changed every hour of the day and night).
Auhhgh! And THAT wasn't the worst of it!!!
The painpills actually made my open closet look like.. legs. spread apart... and not of my gender. Quite disterbing. I also wandered down to the refrigerator "on autopilot" to urinate. Thankfully, my mother was able to steer me back upstairs to the bathroom before I did somthing disgusting to the refrigerator...
That definatly put me as far away from wanting to try drugs as anything else has, too! I wasn't likely to try them anyway, but it's still a good reason to stay away.
