Oxycontin was made to be a 12 hour med, but even allot of pain Doctors are using the 8 hour dosing, as allot of people are finding that after 8 or nine hours there pain is coming back. I know my Doctor tried the 40mg every 8 hours, about 3 or so years ago and it was just to much, I felt drugged out, so at my request we went back to every 12 hours and more Percocets for break through, then I believe it was a year or two ago, that he tried me again at 40mg every 8 hours and what blessing it was I cut drasticly back on the percocets, for a while I didn't even take anything for break through, just get into my recliner when I would hurt. Just make sure that your Doctor understands your pain where it is, what increases it and what you can do to help relieve it, you might even consider keeping a log of your pain, and take it with you to your appointment.
You mentioned that you were tired and sleepy allot during the day, it sounds like you need to have some blood work done to see what is going on. Also, do you have any problems sleeping at night? snoring, or night sweats, or waking up gasping for air, or having the need to move your limbs (especially your legs during the night?) Do you find that you need to get up and go to the bathroom allot during the night? What I am getting at is possible sleep apnea, and you do not have to snore to have it! nor be over weight, or any of the other stereotypical things that they say about people with sleep apnea. You can be any age, or gender, or weitght, often people that take opiate type meds can suffer from Central Sleep apnea! So if your tired allot during the day, and if you have any of these problems with sleeping at night, if you have a spouse or a bed partner, ask them if they notice you having any problems with your sleep, being restless, or any of the other things that I mentioned. If you do mention it your Doctor may you might need to have a sleep study done and see a sleep apnea specialist. Just something to consider, I know I had it for years before being diagnosed, and even then it took them another 18 months before they finally got me on the right PAP treatment, but what a difference it has made in my life!
Anyway I do wish you well and hope everything works out well for you!
