Please don't let me fall off the wagon ...

I'm worried. At the weekend I bought some Walkers Sensations, a large packet - Caramelised Onion & Balsamic Vinegar flavour. Tuesday night I opened them. Last night I finished them. I don't know if Andy ate the middle section or whether I had them all. I don't want to start snacking on crisps every evening, or anytime of day for that matter. I knew they were there. I won't buy them again. But I'm worried that this is the start of my resolve weakening. I must find some more willpower.
