Pastrami and knishes, here I come

I'm leaving for NYC in the morning. For one week. Of sightseeing and eating. Hopefully the sightseeing will burn some major calories. I haven't been to Manhattan in twenty years. My homeland! I promise to climb steps whenever I can. I promise to go to the gym as often as possible. I promise to have just a bite or a lick or a taste of pizza and pastrami and a knish. Dim sum...that's going to be a tough one. I promise that I will not drink regular soda. Absolutely positively. I will avoid all desserts. And that includes Carvel hot fudge sundaes...my favorite. I'll do my best and it will be better than I've done in the past. No sense undoing all the pain and suffering of the last few months. Will my friends notice? Do they care???
What will I say when my friends coax me to join them in overindulgence of fattening foods? Because it will happen.
Will it all be undone in seven short days?
