Worst way to die?
Please... on the right drug cocktail you could ride that out in complete comfort and in a good mood until your dying day.
I know this guy.. you give him an 8 ball of meth.. a pair of tweezers and a blowtorch.. pretty sure he could show you the worst death imaginable.
Drugs could help a little, but I don't know when a person goes completely crazy you know? There is a finite things to pull out of a human being, skin to burn, spots to impale, but this condition makes you worse and worse with no end in sight. Imagine a feverish nightmare as you are awake that you can't escape, and you would do anything to sleep even one hour. Then at some point you can't even move or talk, but you are still afraid of everything near you and see crazy things while feeling your mind going to nothing, regressing.
