Chris--
I know exactly what you are feeling, as I went through what you are about to go through a little over a year ago. You should look back at one of my old posts. It describes my surgery in detail.

Questions answered and recovery part 2
I had the same fears as you. I was worried about the pain as well as how the recovery would be. I was also worried about if my surgeon would cut too much or not enough, though I trusted him and thought he was great, I don't think anyone can really let go of those anxieties and fears when it's our own bodies we are talking about.
So I have some advice (very practical simple advice to make this a bit easier)
First of all, follow all pre-surgery directions and DON'T drink water unless the doctor tells you that you specifically can. I made that mistake and they almost didn't do mine that day! So glad they did.
Secondly, take a pillow and a blanket in the car with you after the surgery, it will be a nicer ride home!
Third... I didn't do this AFTER my surgery... but I was still feeling the pain killers that they gave me afterways, so I said that I didn't need more. BIG MISTAKE. My butt hurt all the way home and then I had to wait another hour while my dad went out to get my pain medication. The lesson here is, if they offer more pain killers, take em!
Obviously, take all your jewelry off at home. My earrings are gauges and are semi-permanent in my ears. Basically I can't unscrew them to take them out without a pair of pliers. It sounds brutal, but its not. They ended up taping my jewelry to my ears!
Bring a good book! They will give you a bag for all your clothes and belongings. I found it distracted me while I was waiting to be taken in for the actual surgery. Helps take off the anxieties.
Don't force that first BM. I tried to and it hurt, and then as soon as I didn't it was fine!
Don't worry.

I know your scared now, but its going to be totally worth it. My recovery really wasn't that bad. It was pretty much a week of feeling yucky and then I was fine. You're going to get through this and once you do, your going to feel like a million bucks! It will be totally worth it. :loveheart:
I'll be thinking of you!
