Hiya, Hope all goes well! I had my most recent lap 2 months ago.
I took all my jewellery off, but there were women on my ward who left their rings on, and they then taped over it to secure it, but I didn't want to risk it going missing.
Food wise- you may find it difficult to eat at first when you wake up after having the oxygen tube during op it can leave your throat quite dry!! I took flapjack in as my snack but just couldn't get it to go down. Personally I would advise if you are able to have something smooth. I was offered a yoghurt by the hospital staff, but if you've got someone going in with you then maybe they could bring you some yoghurt or similar for when you wake up. Just a little extra energy from food can be helpful!
Peppermints/peppermint tea is good for any trapped gas pain in your shoulder.(And when I got home I found a warm hot water bottle really helped with that too).
As for your downstairs, I had a full wax 2 days before, but if you've not had that done before then shaving is just as good, just means it's easier for them to makes incisions wherever they need.
As ladies have said before comfortable clothes are so important. I found it quite difficult to stand straight for a few days after and difficult to raise my arms, so I found cardigans better than jumpers/hoodies/t-shirts etc. Slip on shoes that way you don't have to bend down to tie them etc.
Work-wise it does depend on your job. I work in an office and get lifts to work with my colleague who lives 2 miles down the road from me. I had my lap on a Friday and then had the following week off. I went back in feeling tired but glad to go back. My office were very understanding of what my lap was for, and my limitations throughout recovery so I didn't have to do much for a couple of weeks after returning to work. I would suggest if you have to do any lifting- take more time off!
As for at home - will you have someone with you? I was hungry (and so thirsty) the first night, but after that wasn't up to big meals, so easy to reach snacks are great for the first few days. I also made a box of everything I could possibly need during the day for when my husband went back to work. Meant I barely had to move all day!
Hope these are helpful - the ladies above have pretty much covered it
All the best x
