A confirmation question...or 2
I saw an earlier post that the SI cartos are 100% PG is that correct? Seems I might be one of the few that can't do 100% PG. That sux.
What problems are you having that make you feel like you have a PG sensitivity? When I first quit analogs there were a number of withdrawal symptoms that I mistook as a PG allergy: Cramps in calves, pain in kidneys and sternum. A much-increased water intake and time made those all disappear. I also went through a bout of heavy crud coughing and congestion (like a bad cold) about two weeks in which was simply my body's way of clearing out impurities.
You make an open wood frame, lay it on the flooring, and put the dry ice inside. Freeze a spot, move the frame to the next spot, while you get up the brittle spot, as it freezes the next one. Sounds intriguing, no?
