I had my gallbladder removed 10 years ago after 6 months of weekly attacks.
My op was for 7am... when I got to the hospital, I was given a gown, and paper underwear (sexy) and not long after, I was given tablets which had a sedative effect. I then had the catheter inserted.
In the theatre they put white stuff into my catheter and I went to sleep. All I can remember is waking up feeling like I'd been hit by a truck (I don't take anesthetic very well).. my throat was a little tender and I could feel my tummy was bloated (this is apparently from the air they put into you?) I went back to sleep, woke up again in my room where they gave me my stones to keep in a jar, and they washed me down a little (I had been sick). Later, I was told to get up and walk to the toilet with a nurse, and that was a little painful but I managed it... I had to get up and walk around every day. The drain in my stomach was a nothing really... I remember being really really paranoid about them taking it out, I cried and told them they weren't allowed to because it would hurt... it didn't hurt a bit!!! lol
I was in hospital for 3 days... and when I got home, I had a 5 month old and a 4 year old to look after... I didn't pick either of them up for about a week after I got home, and then it was only my 5 month old. I didn't drive for a few weeks either. After a week I was fine though, It was a relief to not have the attacks anymore too!!!
You'll be fine Cass... wishing you all the best
