I want to know the answer to the following question:
Why did Feynman give up alcohol?
All the background I'm provided with is that "Somewhat embarrassed by his actions, he largely sidestepped the issue when dictating his anecdotes; he mentions it in passing in the "O Americano, Outra Vez" section, while the "Altered States" chapter in Surely You're Joking, Mr. Feynman! describes only marijuana and ketamine experiences at John Lilly's famed sensory deprivation tanks, as a way of studying consciousness.". Is that enough to answer the question?
Answer: no
