Sorry to gatecrash!
I'm using the Schultze B&P without the F1, but I take OxCgen capsules (oxygenated/activated? Magnesium oxide) which certainly promotes visits to the loo, sometimes too often and loose though depending on how many caps you take. I am being cowardly and only taking one B&P dose a day as I don't want to get constipated, and probably because of this I haven't passed any mucoid plaque yet. When I'm feeling adventurous I will probably increase the B&P and then probably the caps too.
