Yeah, Colonix rocks

Did it twice - the first year, one month, the 2nd year, 2 months. First time was the most dramatic as far as what came out. 'Seeds', worms, sacs, you name it, half expected a miniature dinette set that the parasites bought to come out.
Don't want to get graphic but actually had to pull something out of my butt - 3 times. Scary but as we always say, better out than in.
Not cheap but definitely worth it.
