So im new you DIY vaping and i wanted to add some flavor. i have made my own passthrough out of an old disposable e cig just for now, and i have started to make my own liquid. now i just built my passthrough and i was testing it using a 70% usp glycerin from CVS and 30% distilled water mix. and this tastes absolutely horrible. its like chewing on those perscription pills that your supposed to swallow. am i doing the proportions wrong? is there a way i can flavor my mixture without adding any nicotine for now? and can i use anything like vinilla extract to flavor it? sorry if im asking dumb questions, im very new.
