I can't speak to Mexico specifically, but here are some items I found really helpful when I was sleeves 3 weeks ago:
1. Electric heating pad
2. Sleeveless nightgown
3. My favorite pillow with a colored pillowcase (so the nurses knew it came from home)
4. Brand new pack of underwear (just felt good since I couldn't shower until it was time to leave)
5. Flip-flops for walking around. The socks with grippies just didn't do it for me.
6. Check-list of phone numbers for my boyfriend to call to let everyone know I was ok. I divided it up between "Text" and "Call" and included my closest friends, parents, and work team. When I was in recovery he was getting all the congratulatory/good luck/rooting for you notes on my behalf It was great to fully wake up to.
7. Loose yoga pants for going home. Your tummy may be bloated from all the gas used during the procedure.
8. Biotene. Your mouth gets dry from surgery and you may not be able to get up to brush. The minty biotene covers you for both
9. If you use a CPAP and your hospital allows you to bring your own, DO IT.
I had a strong reaction to the anesthesia, so I slept for basically the entire first day. The second day I was able to stay awake and alert for longer stretches, but not enough to read or watch tv or use my laptop. I used my phone a little to check Facebook and Pinterest, but I barely remember.
