Since you have leaky gut and allergies, yes, I would suggest you do this. You could see if the tech is open to negotiating something different, more particular for your needs, as this really seems like a lot of money just for the little bit of extra herbs. And why an initial consultation fee? Most techs only charge for their time - the actual colonic - and don't require an initial consultation. Tell her you're already under the care of a healer and just need to be CLEANED OUT ASAP and that she may lose you as a client if she doesn't get wise! ;)
You've been adding ginger tea and garlic and actual ginger to your diet anyway, haven't you? That's better than pill form. Sheesh.
Do what you can to get 1-3 colonics then get an enema bucket setup and kiss her patootie good-bye!!! :)
