One can train themselves the suffering brought on by withdrawals of cold turkey. What I did in a matter of days one can taper off in a month...but I did if in a couple of days and I'm ready to use again! I use drugs a lot then stop completely, suffer, then repeat, it's part of the process. I have never been able to taper, it's like, "okay I dont feel good, this sucks, I might as well just go all the way since I'm not having a good time"
Yes I might be bias because i could never tapered off in my life. If I have any drugs left to taper , I will just use them to get a buzz. When I run out, I can withdraw. After so many withdraws you become used to it. There's nothing "problematic", accept the suffering is part of life, in exchange for happiness .
The beauty in this there is no uncertainty, you know when you use, you feel good, your day will be great. When you don't, your day will suck. Thats called being completely control. More control than non drug users, they could have a loss of a loved one and they will be sad. But me, a drug user? No my day will be great NO MATTER WHAT unless I decide not to make it that way!
Tl:;dr go cold turkey, if you suffer..keep going till ur 100%...then go use a lot and ct again, and again till you no longer perceive it as suffering!
