@kelly Good luck! You might want to go in barefaced the first time to get used to what to expect, and try lidocaine gel on later sessions. It helps me a lot. Also, take three ibuprofin and with a tall glass of water two hours or so before.
Laser's a huge pain, but it's really a time and money saver. I still have to shave six sessions in, but I only have to shave every other day, and my beard shadow is much lighter. What still grows is very blonde most places. I'm saving myself that time and anxiety in exchange for a few hundred dollars.
