List of neccessary items to bring

Edit Post

Hello everyone , hope you are all doing well. As i see there are plenty of veterans here who already did the procedure. Would you say few words about all the things you should bring with you especially for international patients: like physical stuff -casts and bandages to relief pain, all the physical stuff that helps. Vitamins&supplements&painkillers best working.
All documents, clothes and stuff to bring with you.
How to go pass the time easier- books, tv, Ps??
Other things that you would thought are important?

Hi wannabeidol , thanks for your reply,
What do you think about Advil(ibuprofen) as pain killer? Will it be strong enough against the constant pain?
