I've pretty much only vaped Strawberry and strawberrI had some serious health issues like metabolic syndrome, caused by a medication (which then triggered diabetes), & quit vaping for almost a year. Since then, lots of flavors I loved, specifically Strawberry milk/creams, taste TERRIBLE to me. Not like vapors tongue, but actually burn my mouth like peppers and spearmint toothpaste, and I can smell it from the bottle, on my breath, & taste it from a drop. I ordered $100 of concentrate from Europe and 95% was in pg, and those all have that horrible taste to me except 2 flavors in vg base. It's happening with other flavors too. I recently read another lady's comments about this same thing, and am wondering if anyone else noticed a big change in their response to certain flavors or pg based ejuice in the last year?
