I've only seen the episode where she tried to explain OPKs and got insanely annoyed and haven't watched since.
I love Guilliana and Bill. A colonic is wehre you go in an medically get assisted in removing waste from your system. Basically you take a really thorough poop with the help of water and a tube and a medical staff member.
Not sure why they recommended it for TTC, I have to watch last nights, it's DVRed right now :)
She's a little annoying, but I do love the show. I usually miss it when it's on, but if I see it in re-runs, I try to catch it.
I love that they are TTC right now.
I didn't see the episode, but I was looking at doing a colonic...however it's a little risky, you need to do it more than once, and you have to make sure you go to a reputable person.
Julia Indichova also did it in the book Inconcievable. My DH wouldn't let me :)
