Oh my...I lost my will for a moment and ate a whole cup of cherry vanilla ice cream! (My boyfriend got a quart for himself and I spied it while having a big PMS craving!)

What should I do? In the past, I have made myself sick, and I REFUSE to ever do that again...what should I do to counteract it? Drink lots of water? Work out in a little bit? (If I work out right now, I am sure I will feel sick, as I feel sick already from eating it!)

EEEP!
