A few more things to note before booking: the process basically takes a whole workday. I was lucky enough to get to do this for work, but if you can't get away Monday through Friday, be prepared to spend basically an entire weekend day at the salon.
But, as Jeanise warned, if you're the type of person who likes to go wild on the weekends, maybe don't book a 10 a.m. Sunday appointment. If you come in hungover, you'll be dehydrated, tired, and genuinely more sensitive. This can all affect how much your bleach hurts (more about that later). Basically: don't be a hot mess, which is just good life advice in general.

And just like you would for a Brazilian, don't book during your period. "Either go a week after your cycle, or a week before," Jeanise advised. This is because your body pumps out more hormones to help you deal with your period, and one side effect of those culprits is extra skin sensitivity.
My skin can be a bit of a baby even when I'm not PMS-ing. Like many women, I have been known to pop an Ibuprofen (or two) before any wax appointment. I asked Jeanise if that would help. "Sure," she said. "Pop a paracetamol before you get in, or take two during the process."
