First, congratulations! Just had surgery on April 18th.
I was most nervous that something bad would happen during surgery. But as I laid in the hospital bed right before surgery, I realized that the staff was just at work and calm, and this was an every day occurrence for them. I had to trust that they were competent and if they got me through the surgery I could do everything else.
When I woke up from surgery, I barely remember anything until after I was in my room. I was in a lot of pain [all over my abdomen] and very grouchy [light and sound annoyed me], more than I expected. Sleep will happen in spurts while you're in the hospital since the staff should be checking in on you every hour or so. Lots of pin pricks [blood sugar checks], blood draws, blood pressure checks, pain checks, medication, etc... Don't be afraid to ask for pain or nausea medicine! My Dr. gave me a pain blocking shot [lasted 3 days] during surgery which helped tremendously, but I still needed oral pain meds. So what hurt most was coughing and sneezing... pain was worst for about 4 days and got a LOT better afterwards. Walking [with a walker, because I was very dizzy] helped believe it or not, and the next day I was ready to go home and sleep in my own bed. There is also a lot of urinating because they're pumping you full of IV fluids [but probably no number 2 for a while, since you're not eating and a lot of the meds cause constipation]! The pain was very tolerable even though I was grouchy. Best of luck! Sounds horrible but it wasn't really.
