No, I don't think they'll go away overnight. It should be just like a normal breakout and take a few days (depending on how fast you heal from pimples). But you shouldn't keep breaking out, once after the first peel should be all. But it does vary from person to person I guess. I'd try doing it when you have no plans for the weekend, just a lazy weekend, and do it on a Friday night so you can see how well your skin responds.
