it really depends alot on how much H you have been using these past 4 days. But if I assume you are using an "average" amount of heroin(whatever that is), I would say that yes, you will have withdrawals, but they will be minimal. If you have been using a massive amount of heroin recently, then the withdrawals might be somewhat intense, but I doubt it....and if you have barely been doing any H I would say you might nt have ANY withdrawals. Like I said...it all depends on how much you have been taking.
whatever the WD's are....they would definitely not be as bad as withdrawing from a 12 month addiction. you only were taking them for 4 days.
