The nausea beginners get when trying heroin, will it return to a experienced user if they abstain from the drug for some months and then tries it once again?
for me it never came back regardless of tolerance. I would throw up from oxy and shit when I was younger (like 14-15) but after I got past 30mg without feeling sick I never felt sick from opiates again.
Yeah it can come back, but if you were a long time user, it also goes away a lot faster. Your body gets reacquainted to the dope pretty quickly when you've been at it a long time.
It varies, but definitely possible. I went years (daily use) before developing nausea from opiates. If it was bad before and your tolerance goes down, it could very well come back when you use again.
I didn't use for 2 weeks and I threw up after my first hit. Depends on the person I guess. But The above poster is right Dramamine is wonderful for that.
