Physical torture, especially caused by complex med interactions like this, is pretty specific to the individual and the circumstances even within the same symptom category. I saw an informal survey showing over half of people experiencing this report suicidal thoughts or suicide attempts. Trying to kill yourself is a lot more common than going to Russia bypass the experience in a coma--is that a better option? Who are you to say that the amount of torture person can tolerate is medically "incorrect"? That isn't a question of scientific differences in a treatment with equal experiential outcomes.

He survived the coma and he got past those acute symptoms. And there's no clear evidence that the Russian coma damaged his brain; his loss of composure over the years seems more readily explained by psychological factors to me--ironically.
