I've been satisfied with the mags I've received from LFP (bulk) and Auto (small Amt to check for anecdotal variance).

they don't have much of an active effect other than making you not sick. if you're committed to it, you need to be active for weeks and never be idle. Set a rigorous schedule and record your dosages. Bed early, rise easy, gym, shower, breakfast, work, healthy dinner, hobbies, leaving your place just to do something other than being idle. And repeat, for days. Maybe weeks. That's where I've failed and need to improve on a future taper
buy a time lock safe or give any other opioids to a trusted friend to hold onto, bc they don't totally erase one's mental or behavioral cravings. Depending on how long your use may have been, your actions to dose opioids might nearly be autonomic (or will be so psycho-somatic you miss just the behavior/ritual of doing a line of 0xУ or н or whatever your DoC is)
