My response isn't regarding your fast and TOM (although your symptoms very well might be related).
I just wanted to share that *before* I started taking Evening Primrose Oil caplets I had AWFUL periods! PMS was just terrible and the actual period was worse. The cramps were really bad. I have taken EPO for 2 months now and my peiods are NOTHING to me. I still bleed for 5 or so days but with NO cramps. This supplement has been a miracle for me!
