So it has improved! Not 100% but I have gone from everyday frustration to maybe once or twice a week, and only for short periods, not for hours if not all day. I think it is the oil pulling- coconut with oregano oil. Then i also took another course of Polaramine to help dry things up, after having a break from the first course. I still get a blocked and / or watery feeling in my upper nasal passages and green gunk sometimes comes out when I blow my nose (which makes me think infection of some kind) but the last few days the gunk has become less green if at all, and the extra green did coincide with me moving from oil pulling once a day to twice a day so maybe it has been clearing everything out. Have some ear candles so trying that soon too.
