How much control do you have while on LSD?
Control, like as in control over your thoughts/actions?
Well, if you have good stuff it'll be tough to act normal around others.... so i would recommend doing it alone or with 1-2 close friends. But all those stories about thinking you're an orange and using a knife to peel yourself are total myths.
Your thoughts are unusually lucid, and you'll enjoy a completely different perspective on things. The visual hallucinations are incidental, really.
It's tough to explain, but if you have any other questions I'd be happy to try and answer
