Which drug made you go "I need to do better, STRAIGHT UP"? and it was an actually benefitial realization.

Mine was ketamine; never been in no K-hole, but it was real as it gets; wasn't afraid to hurt my ego or ask myself questions I'd rage at, if someone else asked. Now I'm confident(progressively) and don't fear judgement anymore because I've understood that "whatever anyone thinks about anything"is on them. It has nothing to do with me realistically. I've heard that quote millions of times but it just recently made sense; crazy! But obviously this is too good to be that easy, I fear sometimes that I'm just being delusional EVEN with proof because this shit is drugs after all.

Anyone else had a similar experience? Could be any substance.
