I found for myself, avoid sugar and caffeine anywhere NEAR that time of the month (until Day 1, then everything is good). I restrict it a good bit now anyway - that takes care of any emotional symptoms. Mine isn't bad anyway, but I find that things I usually would brush off - things that honestly bothered me during the rest of the time but I'd let it go, would be aggravating enough to speak up about (sometimes in a pretty rude manner).
