That is what I started doing since I quit doing physical work in the early 2010s....week long scripts when I absolutely need them to have any quality of life.
The last time I was in full on hard-core pain management was in feb-sept 07. I hurt my lower back really badly while still working in building and flooring contracting, and had to go to physical therapy for 5-6 months. I was on two 30 mg time release morphines, and 4 1/2 percocet 10s along with gabapentin and muscle relaxers every day. I told the Doc in July that I felt like I could start weaning off, so he gave me a schedule to reduce weekly. I made my last month of scripts last 9 weeks....that really helped with the withdrawals.
I knew it was going to suck, but I literally wanted to die in Feb until I got on that pain relief regimen...it got me through the worst stretch and helped me get through the therapy.
I am more afraid of feeling that level of pain again than I am ANY medication. I'd rather be chemically dependent than want to die because the excruciating pain NEVER stops.
The day I took my first time release Morphines and Percs I wanted to finally get out of the house and do something fun again, so we went to Honeymoon Island State Park, and I actually got down on my knees in the middle of Honeymoon Island Beach and thanked God that the pain was gone and I could walk and move around again.
