Opioid withdrawal can be easy if you catch it early and have access to some medicine to help you out (For me, at least.). But just because it CAN be easy once or twice, it doesn't mean it's easy in general.
In fact, having an easy withdrawal the first time meant I haven't learned my lesson.
After a year off of opis (had a 6 month oxy habit), I just stumbled into withdrawals once again after smoking H for a month with barely a couple of days break every now and then.
It's not that tough now either, just feeling some mild body temperature anomalies and irritability. It's so mild, that I just ordered a couple points of H for tonight. That's definitely not smart.
So don't fall into this trap. The psychological withdrawals are real, and they're gonna push you farther and farther into the habit if you let them. And when you're shoulder-deep in the habit, it's gonnna get magnitudes worse.
