Help. What to expect

Hey everyone I was wondering if anyone in here could help me prepare for what I’m in for. I’ve been using (snorting) 5mg oxy since October and looking to stop. It started as one or two pills a day back in October and has got to closer to eight or 10 pills a day now. I don’t know if that’s a lot or not and I don’t know what the come down for detox like anybody else been in a similar situation to the other side?
