I think one of the biggest things you can do to make healthy choices about eating, drinking, and your weight is to stop letting food control you emotionally.
(And believe me, I say this as someone who has linked food with emotion for a long time.)
I think it's normal to feel guilty when you go over your calories at first, but at some point you have to own the choice. When you drink, you are CHOOSING to consume those calories, just as you CHOOSE to eat a chocolate bar, or a piece of cake, or a cookie.
Now, mind you, I drink. I had a couple of beers last week with dinner, and I had vodka last night. But ... I CHOSE to drink. And last night's vodka I figured into my calories for the day and didn't go over.
I don't feel guilty about it, any more than I feel guilty about eating burgers and drinking beer on Thursday. I was a little annoyed with myself Friday morning when I weighed in, but I knew I would be.
If you're eating or drinking something and you feel guilty about it, maybe it's a sign you shouldn't be eating or drinking it ... right?

And if you choose to continue doing so, then make that choice and own it and move on.
IMO, that's the healthiest way to deal with it.
