Im an addict, i had a long stint of 2 years clean and than relapsed. The last year ive been using off and on. Id say anywhere from 2x a week to once a month with a month or 2 of total abstinence. Oh i forgot to mention its heroin that im using. I used about 3x in a 8 day period. I stopped and experienced very minor withdrawals. Just basic sneezing, tired, and tossed and turned a little in bed, still slept 5 hours though! Ive been sober 6 days now. im wondering if its safe to use do you think id experience any withdrawals if i used just once ???
