This time around Oxypowder is making me nauseaus..

I just started Oxypowder again this week for prep of a Liver Flush and upon taking 4 caps and 10oz or so of water, I get instant nauseated. It feels like the Oxypowder is stuck in my throat and on its way back up and it actually takes some effort to keep it down..

what the..? Am I just really toxic for some reason? I'm probably pms'ing (late actually) if that has anything to do with it.
