Two juice orders ago I switched from 50/50 to 70/30, looking to get better flavor. The first order - all was fine. But a few days ago I got my second order of 70/30 (assorted sweet & dessert type flavors) and I'm finding that the vape feels harsh and inhaling makes me cough (especially in the morning) and creates throat/chest discomfort, actually very similar to smoking. :-( I'm assuming the PG ratio is too high for me ... sound right?
