15 mnths. 100% PG or 75/25 PG/VG if I have VG on hand. (Wilton's only) Approx 1 Menthol drop per mil in everything. I vape non-stop 3-5mls/day depending on what equipment I'm using. I primarily exhale through my nose.
Improved sinuses, sense of taste and smell. Slight dry mouth if I don't drink enough. Occasional dry nasal passages but nothing severe. Only other adverse reactions I can think of is reduced concentration/cognitive ability/motor skills and an increase in absentmindedness/mood swings, but have determined extent correlates with nicotine strength. Livable effects at approx 11mg liquid, but my job doesn't require too much. Any lower in strength and I become a hazard.
10 mnths for my Gma. She prefers 60/40 PG/VG (Wilton's), non-menthol. She vapes approx 14-16mg strength non-stop approx 3 mils/day. She reports an increased ability to go without and not have panicked obsessive thoughts about needing to smoke or vape. Myself and others have noted she used to have horrible wracking coughing fits that were getting to the point she couldn't even carry on a 5 minute phone conversation without an episode. Those have completely disappeared. No one who knows her, including her Dr has any desire for her to quit vaping.
At present, she isn't reporting any other issues good or bad.
