I'm wondering how exact the timing of your PIO shots have to be. We normally do the shots at 9:30pm. But on Saturday, we have tickets to a Broadway show at 8pm. The show will last to 9:40pm. We would get home between 10 and 10:15pm. Do you think we could wait until we get home or should I bring it with me and do it myself in the bathroom there? Or should we inch up the time by 10 minutes each day before it so that it's closer to 10PM and then inch it back down to 9:30 again?

Thanks!
