Actually, I don't remember the surgery.
For me, the anxiety leading up to it was worse. Don't get me wrong - I am only 3-1/2 weeks post-op (acdf c5/6) and I have had some intense pain, especially while trying to sleep. But anxiety can really mess with your head, not to mention increase your pain levels!
If you have truly given this serious thought and made an informed decision that you need to have the surgery, then pray about it, have other people pray and then try to relax.
The pre-op drugs help a whole lot, to relax you even before you go in. And the drugs post-op (PCA machine) are wonderful. Use them as much as you can before they kick you out of the hospital. Then, when you get home, take all the drugs they give you.
This may sounds strange, but I am an RN and I know that the drugs are prescribed for a purpose and they do what they're supposed to do. You should take them routinely (every 4 hours) rather than just when you can't stand the pain. If you wait too long, they don't work as well and they take longer to work. You will find yourself weaning off of them in a few weeks as you find you need them less, but don't rush it.
I find it hard to believe that this much time has already passed for me. I would tell myself in the days leading up to surgery, "four days from now, it will be over and you'll be home," "two days from now, you'll be finished," "24 hours from now and it will be done," etc. Time really does fly

But I did pray a whole lot, and that helps too!
Good luck - come back on the 13th or 14th for a minute and let us know how you are.
