Too funny! Thanks for the neti pot vid! The friend who turned me on to vaping has reccomended one for years for sinus issues, but I could imagine doing that to myself, lol. Now that I see, it doesn't look all that bad.
Anyway, Zodiak, I have found myself having the same kind of problems whether I use VG or PG. There can be many reasons, but usually it means either my cart is getting to compacted and/or gummy, or my battery is losing power, or I am overheating my atty.
Or a little of all three, lol.
Also true that I tend to get used to flavors over time and become less able to pick up on all the nuances anymore if I vape them constantly....though it seems to have more to do with keeping my device working at peak performance.
For best flavor, I keep a 510 atty I have removed the bridge and wick threads from on hand to use with my 3.7 battery.
I have discovered that I can look down through my drip tip and can see the coils if they go red. If they are red, it means they are dry and I need to add about two drops of fluid, then I will see no red, just some wisps of vapor...and then I vape away!
I get very full flavors this way. The cooler my atty, the better the flavor.
It also helps if I hold my tongue tip up and let the vapor flow over it.
Be aware also...if you suck in overheated vapor or even just air, it will kill your ability taste for awhile, too.
