Recovered from wedding gain - but was it worth it?

I have finally recovered from the gain that happened when I indulged in the two days of my girlfriends friends wedding. 9 days later. That's a lot, more than I expected it to take. Was it worth it? Probably not. I really need to a) make sure that I don't eat too much during these 'off' periods and b) I need to make sure that when I am over the event, I need to really focus on losing weight and probably counting kilojoules.
