over the last couple years, i seem to catch a bad head cold the day after surfing sometimes. it usually lasts 2-3 days. i noticed a pattern that it seems to happen after a surf, if my nose doesn't leak water when i am done surfing. i am sure all of you know the infamous 'drainage' of salt water that comes pouring out after a surf. i am pretty sure, the head cold comes from water that does not drain from my nose. does anyone have any tricks to freeing your nose of water? i tried a pot, but it didn't really work too well.
