Great thread, Doreen! I find the same is true. I've always wondered if it was hormonal, or just due to the fact that I feel like CRAP during the 1st 3 days so I don't push myself as much (for reasons only you ladies--or should I say ladies who have 3 or more children--will understand....LOL!) Mid-cycle I go great guns because it's the time where I feel like I've got the world by the horns--it's all mine!

I've also wondered if there's a depletion of iron (since the red blood cells carry iron, thus oxygen), and that contributes to the sluggishness too... I guess that's another important reason for supplements for women.

BTW, Mellie--the cycle begins on Day 1 of the period.
