Balance??? How??

Well I had a great month where I ran 125 Kms in 32 days. I lost 7 pounds and was feeling great......then I went to Cuba with 15 of my girlfriends and fell off the wagon.

I have been home for 5 days and have eaten out every day since I've been home....and only ran 10kms. I am mortified at my behaviour. As a yoyo dieter I feel like I'm at the bottom of the barrel again. I wonder why on earth I can have endless energy and eat well for a month and then drink and eat enough for a small village????? When will the battle end.

I know I need to suck it up and get my *kitten* in gear. I want to have a good life of moderation....not so extreme. I find I am in all or nothing.

How do you find the balance????
