challenge starts tomorrow

I am about to start my $2 a day for 3 days tomorrow morning. This seems like a difficult challenge after reading through the posts. I like to snack all day and especially eat a lot of candy. I think it will be difficult to come home from class and not want to just grab something from my cabinet to eat. I have bought rice, ramon noodles, some beans, and a can of corn because it was cheap and I am not a big fan of beans anyways. I'm looking forward to the task at hand.
