This is an awesome thread topic!
LOL, the only things I've ever had waxed are my eyebrows once. It was actually a nice experience at a day-spa and I remember being amazed at how much of a difference that little amount of precision grooming could make!
But, I'm unwilling to spend money on that type of thing on a regular basis, so it was a one shot deal for me.
And, re: irritability, etc. ... for me PMS has always meant something more like a little phase of being relatively depressed. Since I recognize it as PMS, it's acutally not so bad sometimes... just recognizing it as a passing phase. It was god-awful in grad school and not so bad lately, for which I'm very grateful.
I've never been on birth control in my life, so things are free-wheeling for me and relatively predictable. And for me, it's really true... if I'm living in a situation where there are a lot of women sharing one bathroom... I will regulate to be on the other women's cycles. It's honestly pretty fascinating.
