I haven't added the Bentonite yet...in fact, I stopped the shakes for the last two days because I've been doing an apple fast in prep for a Liver Flush tomorrow night. I'll start the shakes again a day or two after my flush and will be adding the bentonite...will keep you posted.
I'm also curious about the O2 stuff...but I try not to do too much at once so that I have an idea of what each cleanse does so that I can recommend them to clients per their needs. Since I'm adding the Bentonite this time I'm going to hold off on the O2...but you might want to give it a try...it might speed up the process.
Keep us posted about how the HH works for you. ; )
