Being of a NeoPagan stripe, I confess that periods don't bother me and I've learned to love, honor and accept them. That said, when I was younger, I used to have severe cramps that kept me bedridden & barfing a lot. However, my body now can have a period with no problems. I also think there's a psychosomatic component. If one changes their thinking about periods (like I did) it does ease the pain a tad. That's not to say one shouldn't get valid medical treatment for PMDD, of course. Mine just kinda went away with time.
Now, all I have to contend with is some bloating & irritability, I can remedy this with some nice teas.
