Hi there,
I just had my sleeve done 6/18 and I'm 4 days postoperative. As far as what to pack I wouldn't overdo it. I took a lot more than I actually even touched while in the hospital. The things I brought and used was Chapstick, phone charger, small comfortable pillow for traveling and the clothes I wore home are the same ones I wore to the hospital. Each time I walked the halls I wore a second hospital gown overtop. I wast able to wear anything else very easily due to the IVs. I also was provided non skid socks but wore flip flops to and home from the hospital
Good luck!!
