HI Allie-
First of all, WELCOME!
I am fairly new myself---you have already gotten some great advice here.
I would just add that when my order came, I put it all in one area in my cupboard/pantry, so that I would go THERE for my meals, and not be searching around amidst other things that the rest of my family eats! Actually, I have not been tempted much at all by other foods--I think when you are so ready and make the decision mentally to do this, you'll really want to. It doesn't mean you won't have cravings, struggles, etc., but you have this forum and your own picture of YOU at your goal, which will probably come faster than you think when you follow the program.
I would also avoid as much as possible eating out the first couple weeks-it helps you get in the groove of Medi-fast and gives you will-power for the times you do eat out.
Water, Crystal Light, Starbucks iced tea w/ splenda--all great drinks!
Good luck and keep us posted!
Marie
