I have read several techniques for the coffee enemas. I lie on my back to insert the enema and stay there for 5 minutes. Then I turn onto my right side for 10 more minutes. I uses to also do the left side, but I found all the moving around made it hard to retain the coffee. I just make my coffee in the coffee maker as that is easiest.
My husband made me a sauna box based on Wilson's instructions. I can use it in the bathtub with a heavy blanket over the opening, or I can set it up in the basement on a temporary frame that we have made. I have no experience with steam sauna, but there are articles on Wilson's site that discuss various options.
