For an occasional/recreational user, is alcohol consumption once in a while harmful for your brain? I googled and i couldnt really find a straight answer, i read somewhere a while back though that Richard feynman never drank alcohol or did any drugs(he wanted to experiment with LSD) because he was afraid it would affect or harm his brain, even if ever so slighty. Is occasional drinking bad for your brain? just when i feel down or kinda depressed or stressed i feel like drinking just to loosen up and relax a little #edit here we go found this on wikipedia "According to Genius, the James Gleick–authored biography, Feynman tried LSD during his professorship at Caltech. Somewhat embarrassed by his actions, Feynman 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. Feynman gave up alcohol when he began to show early signs of alcoholism, as he did not want to do anything that could damage his brain—the same reason given in "O Americano, Outra Vez" for his reluctance to experiment with LSD"
