That sounded like an appetizer to me
Kidding aside, I know exactly how you feel having been there many, many, many, many times myself -- and then some. Those particularly bad instances I seem to have erased from memory. Sometimes they were so horrible, honestly, what you just described as having eaten was really just the beginning of an epic binge.
Today is a new day. Remember that, don't be too hard on yourself, refocus and re-calibrate and don't get on the scale for a while because it's too depressing. Those extra 6 lbs will go away soon. Also, try to determine what triggered you last night...it may help prevent in the future and most importantly, help you understand yourself better.
Xoxo and a big big hug.
