Yeah, I definitely understand the 'not drinking calories' thing, but I make an exception when in a coffee shop. A cup of coffee with cream (or a latte) is about a billion times better choice than a pastry and it makes me feel both indulgent and 'normal', so I don't feel guilt about it. For me, it's always been about the experience and not the calories (in that situation).

A big ole glass of OJ? Now that makes me feel guilty!

My point is that your day wasn't a 'disaster' my most people's standards. (Even with the brownies!) A disaster would be eating an entire large pizza by yourself and then consuming the free trial lava crunch cake too. Or finishing off an entire bag of Mini Eggs (not the individual serving size!) in one day. Or consuming a pint of Ben n Jerrys in one sitting and then following it up with a large stack of oreo's. Or filling a plate with deserts from a buffet to 'taste' them all and ending up gobbling them up even though you'd already eaten an entire meal. Or maybe eating all the halloween candy before halloween and having to buy more so your husband doesn't know about it. Don't ask me how I know about these types of days, please.
