Anyone have any advice on how to combat PMS, physical and emotional symptoms?

I feel since AF has returned post having Ash that the symptoms are stronger.

I get bad headaches and nausea plus the moods I get in are the worst. I get so snappy at Df and poor Ash also gets told off over little things that wouldn't bother me so much any other time. I'll also throw things across the room and get very teary.

I hate it so I need something that will help me with it!
