chronic pain
"I use 30 mg oxycodone three times a day.  It helps with pain and keep me motivated to keep working.  I have arthritis and Crohn's disease.  The pills keep my pain in control and interesting the side effect is constipation and it helps control my frequent bowel movement.   This medication is knocking two issues with one stone.   Only bad thing is withdrawal if you run out and didn't get the refill in time.  It's not as easy as other meds that has auto refill, always have to get a paper prescription for each refill.  But the medicine really helped me for years."
