Thank you for your input. I unfortunately don't read german but wiil try a translation program. I got the impression you only take dmps once a month. What is the dosage?I take it every third day for a month and then take a yeast killer (Latero Flora) for a month and repeat the process till I've chipped away at both problems. I only stop my msm and whey powder on the morning of my dmps because I was told that dmps and sulfur is a nono(although I don't remember why).How much do you pay for dmps? I too supplement with zinc but only on the nights of the dmps.
