not entirely true... theres this thing called 'micro dosing' where you take maybe 1/4 of a tab, enough to feel psychedelic effects but nothing that will put you in the 5th dimension. very good for producing music as well as many other things. but yeah on a strong experience you would lose interest.
as for me... to be honest I only got into psytrance through LSD, now I like it perfectly sober of course but at festivals i'll take LSD and MDMA, nothing else, and only once for each drug per festival. i only trip at festivals though, no other parties
