I can sort of relate, mel.

When I was much younger (23ish) my boyfriend at the time gave me the shock of my life when he called me exactly the same thing.

I was doing my thesis in substance abuse at the time (the sweet irony of saying THAT to someone while you're wasted is not lost). I was once interviewing someone at the prison who was in for dealing a few things when I realised he was the old roommate of someone who i was very close to (ex f***buddy), and well, obviously used to get us a lot of shyt. I have played around with much more than my fair share.

But yea we used to get chopped and go to dj gigs most weekends and it wouldn't stop at 6am when the party finished either.

I know a lot of it for me was trying to distract myself from feeling down / blah and it truly was a great escape and stress release from feeling like cat vomit - at the time.

What my bf said basically forced me to take a good look at my party habits and consumption of drugs. I won't lie and say I never touched anything again but i did make a lot of changes. And my roommate at the time was (and still is) heavily involved in it and there was plenty of experimental stuff going around as well. I shudder to think what I might have been taking. But hey, it made me less depressed, i forgot all about being blah, until the comedown

Anyway good luck to you
