Is There a Way to Detox From Long Term Use of Pain Medication?

I have just completed the final of 4 major surgeries (Car wreck) this past month (Neck fusion, knee replaced, 2 hips replaced) over a 24 month period. I left time between each surgery to rehab for the next one (I’ve had 10 total surgeries and I’m now healthy). I am 52, happily married, have an 18 year old son and a good job. I am not emotionally unstable or have deep emotional scars that need to be fixed by going to rehab. For those of you that want to lecture me on the dangers of drugs, tell me that I need help or want to push me towards psychological councelling please don’t waste my time. I have taken my meds as perscribed for 3+ years (Strong stuff unfortunately) and want to stop without going through a 12 step program. I also don’t want to wean myself off over 6-8 weeks. This ordeal is finally over and I want to do this part fast so if you have any thoughts as to how I can minimize the withdrawel effects so I can get back to my pre-surgical life I would really appreciate it.
