HEY! It's okay! Don't beat yourself up! And never try to make yourself puke again! It's a sick thing to do and it can easily become a sick habit that can very hard to stop, and can have long term complications. Trust me, I'm in the health field and see enough bulimics to say this.
We ALL binge here and there!!!! It's part of being human! We are not perfect and no one is, even if it appears that way, NO ONE is perfect and we ALL make mistakes. The most important thing is, GET BACK ON THE SADDLE, don't look back, and MOVE ON. Water under the bridge!
I just binged this morning on cookie dough - probably half the bowl. I felt terrible afterwards because I had worked out and ate a healthy breakfast. But heck, we all do this and I made sure I ate an ok lunch and dinner.
To prevent yourself from binging, make sure you are satiated. Eat protein rich meals, with plenty of snacking in between on veggies and fruits. If you are undereating, or skipping meals, or eating below 1200 calories/day, you ARE setting yourself up for binging episodes, becuase you are starving and will eat anything in sight.
You just had too much candy. That is all. You will put it behind you, make a sensible choice for dinner, and move on.
