I ask my DH to hide all chocolate, biscuits etc away. if I want some I tell him and he gets some out for me. Eg I say please get me two biscuits/three chocolates or whatever and he fetches then.
I find this means I can have some if I really want to but it keeps me from nibbling until they're all gone... which can definitely happen.

! However..... the National Trust property a few miles away sells a vegan chocolate cookie to die for... I think I feel a visit is essential in the very near future
