I'm gonna be a curmudgeon too
I don't want to **** myself up more, but I do want to have that rush. Be it energy boosts, light hallucinations or the feeling of being kind of out there...
Looking for ways to replace that buzz is a dangerous road for guys like me.
'tripping balls' (as you youngsters say) is not a place I want to be anymore.
There are things that will give you a good feeling and many of them have been mentioned here - running, listening to or playing music, laughing, chocolate, acting in a play, team sports - but from your post (your initial one anyway) I got the sense you want a little more than that?
I may have misread you, but if not I'd think very carefully about what you want and why you want it.
You wouldn't be the first person to go looking for a way to get the buzz without the consequences.
I can put my hand for that too, over the years
