Don't feel disgusted or ashamed. Feel proud that you have educated yourself and taken responsibility for your health. parasites are not considered a problem or even a real health issue by the mainstream community- medical or otherwise, so you're already ahead of the game!
In order to expel the parasites from your body as quickly as possible, your colon needs to be cleansed properly- you don't want toxins and bacteria sitting around inside of you any longer than absolutely necessary, so I would suggest that you wait until your Oxypowder arrives before taking your parasite formulation.
A lot of people have experienced feelings of pretty intense toxicity and Sugar cravings as they kill off the parasites (parasites thrive off sugar), so be prepared.
I am also waiting on Oxypowder and Clarkia as the PB Shakes didn't agree with my system.
