@dfoster85 - I remember doing the same thing after my c-section! It hurt so much to get out of bed but I knew that I needed to.
The challenge is figuring out exactly what level is right for you. Part of me wanted to stay in bed. That wouldn't have been good for me, but neither would pushing too hard. I guess if you've had a c-section, it's normal for your incision to hurt, but you shouldn't be exhausting the rest of yourself! Maybe the right amount of activity is the amount that makes you feel more, rather than less, alert and energized.
However you deliver, it's important that your postnatal workout start you off slowly. If you start trying to do fifty crunches six weeks to the day after you deliver, you'll regret it! I suggest spending the first couple weeks back to exercise just walking, stretching, and doing some special postnatal exercise moves from a good DVD or book. Once you feel more like yourself, you can gradually resume your old level of activity. (And *yes,* you can absolutely exercise while breastfeeding!)
