Having a bad day !!!! :-(

For me, it's hard once I get a taste for those goodies to then let them go. But can you find something active to do away from the house or errands, just so you are not around the food? Just remember, even when you think you want something, if you are truly not hungry and can distract yourself for 15 minutes, the feeling will go away. You can get back on track! Do it!!!

You did so well to do a class because you knew you were going to be letting loose a bit, thats dedication so you know you can do well! I think that a bit of indulgence every now and again is essential to a healthy mindset, so drink a lot of water to get you feeling good again, and start tomorrow completely fresh - don't look back or regret it, just carry on with your hard work!

You should log your calories every day. Just because you didn't log them doesn't mean they don't exist! I would go back and do your best to log everything from yesterday.
Personally, I used my first couple of weeks on here just to see what I was eating and when. If I went over I didn't let myself get upset or beat myself up over it. I just wanted to see my habits and my weak spots. I think this site works much better if you are honest with yourself; and that can be really hard sometimes.
Also read the message boards and blogs. You'll find so many people going through the same things.
Most people's habits don't change overnight, it's a process. Let it be a process. Be honest with yourself (I'm on here because I used to tell myself that if no one saw me eat it then it didn't have calories!) but also be kind to yourself. Every day is a new day. It will get better.

I noticed when I do this I'm usually tired and that my body craves bad food to fuel me again (carbs, sweets, sugar)... so a nap is a good idea if you can - and drink plenty of water before you do.. The wines dehydration tendancies do not help this at all.. Hope you bounce back in a jiffy!
