This was an issue, for me at least, before we ever got married. When DH is home he snacks All. Day. Long. I buy groceries on Friday, he will get home around 5 & by Sunday afternoon almost every single snack is completely gone, 70% of the items I had absolutely none of.
He complains that he wants to eat healthier but he REFUSES to eat the fruits & veggies I buy as snacks. Which is great in the sense that I know I will always have something to eat regardless of how much he eats, but I feel as though I'm spending more money than we need to because he blows through food so fast.

We argue about it more often than I'd like to admit. Anyone else' SO a bottomless pit?
