I bring peanut butter with me and buy fresh bread or rolls in the morning ,
go to supermarket for sandwich stuff for lunch and eat at a local restaurant for dinner , I am not a foodie !
I bring clothes I do not love so I can leave them or give them away before I head home ,
Bring a phone you have "retired" , if it gets lost , broken or falls in the river no big lose , and get a local sim.

But mostly go with eyes wide open and enjoy the difference
