Spring,
Something as simple as replacing a beer with a Coke has actually got me over the hump several times this month. One of my biggest triggers is craving a beer after a few hours of yard work (or as I started firing up the grill after said work). Your mileage may vary, but one can of Coke (and I suppose the sugar rush) has eased the urge for a beer enough to get on with my day without any problems. A DQ Blizzard for a reward sounds like a great idea too.
