My period started this morning. My cycle is always irregular, so I'm never quite sure when it's coming. My usual clue is that I'm a weepy, grouchy mess about a week before. But this month? I was a little snappy with the kids, but not weeping over vacuum commercials, or stepping on an ant.
If you've cut the junk/sugar from your diet, or severely restricted it, have you noticed a change in your PMS?
