I once got some coke, that I believe was supposed to be cleaned up by my connect, with acetone... well they didn't do it correctly, and didn't let it purify long enough or used too much acetone.. something happened that wasn't right.. but anyways, it gave me such a bad sinus infection, that had my nose bleeding and stuffed up with mucous.. it burned! and I was unable to sniff anything, which sucked because I loved to sniff oxy at that time, and when I did it just made it worse.. so long story short, it lasted for like a week, maybe a bit longer, and I would randomly get nosebleeds, and at work no less... it was bad! but thankfully at the time, I worked somewhere, where everyone was an addict to something.. so they didn't stress it. But I did, I was hurting bad, and then like after 10 days or so, it just stopped, scabbed up in my nostrils, and in a couple days was gone.. needless to say, I don't think I ever railed coke again after that, and just smoked it until I started to IV.
It is easier said than done, to just "not do it anymore".. not for everyone, but let me tell you.. after I graduated to smoking crack and shooting powder, shit hit the fan before I could even blink... I was fucked! Couldn't stop myself from wanting it everyday after work.. I would get this feeling like, "ok I have money, I NEED to get some coke or crack and do it now!!!" it was odd, like in the morning I didn't have any desire to get it, but after I made tips at my job every single day for years, I progressively became a total cocaine addict! Telling my self when I would come down at night, "Never again! This is my last time!".. it didn't work that way, my brain became rewired to just make me a slave to this drug, psychologically and until I lost my car, and then my job due to not having a way to work.. I couldn't stop, but then when I lost my job/car, I had to stop.. had no way of getting it.. so I did. And now, I am much better, just mess with it, every other weekend, or just say fuck and don't do any for a month.. Just saying, if you are any everyday user, it wont be as easy as just saying fuck it, I am done! I said that, thousands of times... and still when I have money, which isn't as often as I used to, I want it.. AND I have Adderall, which for most would be good enough, but its just a totally different feeling, and I crave that coke rush, that only it can provide.. Good luck, hope you can stop before shit spirals outta control.. When I was just a snorter/occasional smoker of coke/freebase, I told myself " I will never, EVER shoot it!" well... shit happened and I did shoot it, and nearly destroyed my life, between that and opiate addiction.. never know what will happen, never say never.. but I would say stop now, if you still feel you can! Hope it works out for ya..
