I just had a myomectomy 4 weeks ago, and was like you hoping it didn't turn into a hysterectomy. Basically everything you read about hysterectomies here is what the recovery was like for the myomectomy except the hormone problems. You'll probably actually have even more internal stitches w/ a myo I'm guessing as they take things out and put the uterus back together - I had 5 fibroids - 2 substantial ones - that looked like there'd be quite a hole to fill.
I had to drink magnesium citrate for the bowel prep - it wasn't as bad as I dreaded. But, when they said that drinking it ahead of time would ease the gas pains, they lied! I still had all that fun stuff you read about here.
I don't know if your fibroids have caused you a great deal of pain, but mine were - and I already feel WAY better than I did pre-surgery from that perspective. And, my first period was 6 days - a huge blessing - not the 12-14 day stuff. So, that made me not as jealous of these ladies on this site - with their no periods!
You probably won't feel too much like participating in the Thanksgiving festivities, although my first day home from the hospital I felt better than I did for a few weeks afterward - I got a fever about that time that lasted until 3 weeks after my surgery.
And, the nervousness stuff is just like what you read about here. This site really prepared me for most aspects of the surgery - they are so similar. And, yes, I was terrified before surgery and realized I'd wasted too much worry - just like everybody else around here.
There's a forum I've found very helpful for myomectomy recovery at http://www.delphi.com
, then find the The Fibroid Place Forum. Its sort of a mini-version of this one, except there are bunches of pre and post myomectomy folks.
Hope all goes well, and let me know if you have other questions.
