Brother,
Idk if uve been to rehab before but after many stints, psych wards, psychologists, shrinks, etc. I can assure u something, u are not feeling bad cause you are taking a low dose of bupe. You're feeling bad because u are not getting a euphoric effect from it, idk what your drug of choice was before(probably heroin or oxys) but you are longing for it. And even not taking your DOC is not what's wrong with you. You know what the truth is? There's something very deep inside of you, something that bothers you, something that hurts. Unresolved trauma.
That's what you needa work on, u need to search deep within u what is that thing that aches. After you resolve that and find New coping mechanisms and new healthy habits, I can guarantee you will not feel the need to get high. I'm an addict too, I got far too many years dealing with this, I've experienced, heard and seen it all. I'm fucking terrified of pain, of feeling boredom from the mundane life, etc. It's time for you to change that chip mindset and learn back how to live without numbing urself with delicious opiates but at some point enough is enough.
Btw, I don't wanna preach u the dangers of IV cause that's the last thing u wanna listen to. Nonetheless, u needa know a couple things about bupe:
-Buprenorphine is a partial opioid agonist so it's not gonna have that euphoric high like full agonists(heroin,dilaudid, morphine, oxy, etc)
-another thing is that unlike the most commonly injected opioids, Buprenorphine has no Intravenous RUSH that most addicts seek. It's just an instant onset and better absorption
-Now you might know this already but I gotta say it, PILLS ARE DANGEROUS AS FUCK to shoot. They're not designed for that type of route, ure just gonna fill your veins with that gunk and fuck up ur health.
Well that's pretty much all I wanted to say to you, if you wanna carry on go ahead. I'm just telling u nothing good is gonna come out of it.
Hope u find inner peace bro, I know how it feels.
Take care
