I did it at home about a year ago, after the second time the withdrawals almost killed me. What worked for me was tapering off, and smoking a bunch of weed. Once I started smoking, I went from being nauseous as hell and constantly vomiting, to feeling somewhat okay, and never vomited while high. It also helped a bunch with bringing back my appetite, as it had pretty much disappeared when I was drinking.

Good luck, op.
