Not to be a downer, but statistically speaking that is JUST NOT TRUE.

the only likely outcome is a long, ugly, life-ruining cycle of traumatic bullshit, equally traumatic WDs, equally bullshit "SOBER BRO" chest bumping, and a constant risk of randomly DYING due to a single decision to do it one time, with every successful use slowly bringing you back to the top of this paragraph

Get on maintenance. DONT USE IT TO GET BY ON BAD DAYS. USE IT TO GET BETTER, AND YOUR LIFE WILL FOLLOW SUIT

A decade is too long to just use "gay conversion therapy for drug abuse" and beat yourself up when it doesnt work or turns you into a person who doesnt care about anything else.

I've been off Heroin for 2 years. I take 4-8mg Subutex a day, and use meth semi often (most weekends). I've been doing it for 7 or 8 months now, never more often, rarely more than my normal routine ($10 for 24+h of fulfilling, healthy life activities repeat 1-2 more times as needed. Sleep. Eat. Responsibilities. Repeat) My life isnt perfect, but its BY FAR the best it's been since I started using. I'm in great shape, <1yr from getting my Brown Belt in Tae Kwon Do, I have like 12-18 MONTHS of meds saved up (400+ 8mg Subutex) and, most importantly

I can SIT NEXT TO PPL SHOOTING HEROIN (even the good brown kind) without a single fuck given, except for when my IV OCD alarms go off, but that's inevitable

By comparison, I was "Sober, not Clean" (aka bupe only, no IVing, no weed/alcohol etc) for just under a year before I started dabbling again. I was fat, lethargic, REALLY depressed for no other reason, worse than my seizure meds made my childhood, and all I had to show for it was a dependence on coffee..

I needed to get my head straight at first after a 2 year goofball bender, and half a decade of doing what you are, minus those extreme highs and lows due to accepting my addiction as a lifelong agreement I made, and taking the moderate approach to both ends

I'm a lifer. That doesnt mean it has to ruin my life. Maybe it's time to try to make it about the least harm, instead of the last hit
