Given that Alexey Leonov had to partially manually deflate his suit in order to get back in the capsule, and hypoxic death is actually euphoric, a suicide pill doesn't seem to make much sense.
So many questions: did he tape the pill to the inside of his helmet some place he could reach it with his tongue? I presume it's impossible or nearly impossible to pull your arm out of the sleeve of a Soviet space suit without remove part of the suit. Was the plan that he could remove his space suit helmet in the middle of space, so that he could place the pill in his mouth? Was he expected to hold the suicide pill in his mouth for the duration of the spacewalk and be very careful to not accidentally swallow it or choke on it?
