I used to Vape very Heavily Flavored/Sweetened e-Liquids. If fact, that is what made me get into DIY. Not being able to find e-Liquids that were Strong and Sweet enough.
But I Burned Out on these e-Liquids. Because they became like putting Salt on Food. I needed More and More (and More) Flavoring to get that Flavor I was Chasing.
I tired Unflavored with a touch of Sucralose as a way to Break the Escalation of Flavorings I was putting in my DIY e-Liquids. Thinking if I did some Unflavored for a Week or so, that a Less Flavored e-liquid would Taste Normal.
I actually Liked Unflavored. It was like drinking a Big Glass of Water when thirsty verses drinking a Soda. More Refreshing. And my Flavor Burn Out went away.
I also found that with a New Coil, if I primed the Cotton with Flavored e-Liquid and then filled the Tank with Unflavored, that I got an Unbelievable amount of Flavor. And the Flavor lasted for Many Tanks.
Today, buying Unflavored is Very Easy. Because many DIY suppliers sell Nicotine Base in Vapable mg/ml levels. So all a person needs to do is Add their own Flavorings.
Many who use Unflavored just Skip the adding of the Flavorings step. And vape Low mg/ml Nicotine Base. Or, of course, dilute High mg/ml Nicotine Base down to vapable levels.
