Flat tummy after the cleanse?

Hi all,
I still haven't done a parasites cleanse, and I was wondering what are the effects you experince after the cleanse. I imagine even if I didn't examine my feces I would feel that I have no longer have parasites if my digestion is better and I also imagine having a flat tummy after the cleanse.
Do you guys experience that?
How does it feel expelling this critters? I'm still a little concerned but I want to do it badly, no mater what I'll see.. :-))
