I've always done these on a day off. Being that the stupid thing needs to be refrigerated, I'd never subject my co-workers to seeing *that* in the office fridge!!! I hate doing them on a nice day, but on a rainy day - who cares? Stay home, or close to home, and watch movies! Besides, they always have given me one of those "urine hats" to pee in, which is another thing I'd never subject my co-workers to. Yikes!KarenInWA
