Pastries are rough because I like them so much. I've found that when it comes to sweets, nothing beats a 500mL bottle of Coke. It's just sugar and not filled with butter. 200 calories, which is much less than most chocolate bars, cookies, pastries, and other treats.
I have strong self control, so it doesn't happen often, but Coke is my go to if I *need* it. Pastries, I just save for refeeds.
