I had mine done years ago. I was scared as I hadn't had an operation before. I had day surgery.
I got there in the morning, had to put on a hospital gown and my own dressing-gown. Had blood taken, put my own clothes in a locker, sat in a lounge with about a dozen others. I was given a pre-med (sedative), which made me nicely relaxed. They called me in later, I walked into the theatre, got onto the operating table, and was shortly asleep.
3 hours later, (it took longer than usual as I had such a lot of stones, which they gave me in 2 tubes!) I woke up drowsy and cold, in a hospital bed. The nurses were lovely, put blankets on me, make me tea and toast, helped me to the loo for a wee.
I then sat in the recovery longe, waiting for my husband to pick me up. A doctor offered me Morphine, which I accepted, as the pain had kicked in. I went home, was told not to lift anything for 24 hours. My wounds bled quite a bit that night ( 3small cuts-nave (where they take your gallbladder out through), just under right breast, and another in midriff area.
The next day, I felt sore but OK. I mooched about at home, my friend hoovered. I was able to bend to feed my cats. I went out on day 6, felt slow. On day 8, I drove to the shops.
I found that certain foods didn't suit me and gave me diarrhoea (orange-coloured!) which I was told was expected. I avoided all fatty foods for quite some time afterwards. All in all, I've not had a problem.
