Thanks hanna. I just finished a 30 day ( 2 x 15 days) round of Paragone. Never had this problem the whole time. Hmmm since you said they were unpredictable then perhaps they're the culprit but why at the very end of the round and not during? Crazy! LOL! Yeah, my Liver Flush is done so I'm going to wait a couple of days before trying the Oxypowder again. If it starts up again then I'll have to switch back to Schulze. I'll probably do another Liver Flush in a couple of weeks to flush out anything else that might be causing this!
