How did I get here?

About 4 years ago I was in a pretty bad car accident.  A drunk driver ran a stop sign and hit me on the side.  The entire dashboard buckled on my knees.  I was on percocet's for about 2 years and once I realized I was dependant on them, the fear made me quit c/t.  That was the worst 2 weeks of my life.  After having major lower back pain, and test after test, they found that I had deteriorating discs and also severe tendenitis/arthritis in both wrists from playing drums for so long.  I told my Dr. that I had a problem in the past with oxycodone and he thought it was best to give me Norco's.  Here's were it all started again.  I was up to 10+ of these a day and before I knew it, I was thrown right back in the middle of the fire.  I am now on a taper plan and down to 5-750's per day.  I know it's my fault for putting myself back here so I must pull myself out. It's gonna be hell, but if there is no struggle, what do we learn?
