It can be cleared from your system with interferon treatment. But that has a range of side effects that aren't well-documented and occasionally are long term and terrible. Theres a decent chance, at least like 20%, that your body will clear it on its own. More likely if you are female. If you got it, i'd wait and see if your body could clear it, and if not, i'd personally just stop drinking and doing stuff bad for you liver and live with it. Hep C is on the verge of becoming completely curable from what i researched when i had a hep c scare, and you will be fine for at least 10 years, but probably much longer, and by then i'd put money that they have a cure. Currently, interferon works like 50% of the time, more or less depending on what subtype of hep c u got. So its not all bleak news.
Best of luck, and i hope you didnt catch anything and will take this as a lesson to stop shooting drugs or at least stop using drugs around other users b/c you run these risks.
