I suffered a severe nervous breakdown last year that turned into a psychosis (brought on by stress not drugs)... I was going through something very intense & couldn’t sleep for weeks because psychosis made me feel like I was dying... since then there have been strange & perplexing changes to my body that have not changed back.... one of them is that alcohol no longer affects me at all?? Previously I could have 2 drinks & feel tipsy - now it doesn’t affect me at all... have tried to drink and experiment with different quantities to no avail... it’s very perplexing... not to use as a crutch but to not be able to experience any effects at all is bizarre? Anyone had this happen to them?
