It's A Hormone Thing

This 30-something stage has been such a roller coaster emotionally. Lately, I've noticed a few of my friends and I have been discussing it. My hormones are raging worse than a teenager lately. I'm almost at "cougar" status (ok- fantasizing about it, not actually acting out upon it). I even find if I'm at the gym, if there isn't a hot young guy to look at, my workout just isn't as much fun. But then we get the the binge eating and overall bitchiness period of time. I'm just such a pleasure to be around then, and add more time at the weights for me! I'm terrified of the next stage, can anyone say "hot flashes"???
