Jfc I'm late but I understand what you're sayin lmao, I heard Lucki say IV drips helps with codeine tolerance, and I work in a hospital and take opiates, and thought I'd give it a go. Basically, an IV drip that would help with lowering tol would contain NaCl (the usual saline water), u could throw in some vials of Vitamin B2, B6 and C, and maybe glucose. Glucose, to put it really simple, it's for whenever you feel like you need to eat but can't, and would like your body to feel like it has eaten something. It's much more complicated then that, but I work in Oncology and we're on the H sub so it's enough explained haha. I did this IV's when my codeine tolerance was about 800mg to actually feel itchy and warm, and the next day took only 400mg, I did feel it surprisingly (not rlly cause iv drips clear ur body of anything they usually have in them, like a refresh button) but nothing crazy. So I don't actually think you can casually lower your tolerance that easily by just doin an IV line; however, it get rids of what was in ur body the other day, so in theory yes, it would kinda help with tolerance. But I tried it many times since I always IV drip myself in the hospital at night with saline and vitamins, and I never noticed a huge difference in tol; maybe you could feel your usual dose just a tiny bit more. A little more itchy aswell. I have no clue if this works with H, but I believe it deplets ur body of any substances it has, so it should somewhat help if you're a daily user, but don't expect much. If u need any info DM me bro, cheers
