I'm only 3 weeks out so definitely no sleeve expert, but my tips would be:
1) Don't compare yourself to others. As hard as that is, everyone's journey is so unique and personal. It will drive you crazy.
2) Remember to keep your eye on the prize. It gets discouraging when you are in a stall or losing slowly. Just remember, you really won't be the only person the sleeve doesn't work for if you work your sleeve.
3) Get your Water in
4) Get your Protein in
5) Remember to enjoy life. Have fun and start enjoying all the things you missed out on being overweight.
6) Listen to your body. It's a good source of info.
Good luck and keep us posted.
