Hi. Using standard cartos right now (not in a tank) as I wait for my VV 3s to show up. It seems like, all of a sudden, all my filled cartos taste bitter. Not sure I'd say 'burnt' but bitter (obviously taste is subjective). I've got carts with Joosy Fruit, PB & Banana, and Coconut Cream Pie, that all started tasting awful at the same time. I first tried to make sure that the carts were well saturated, but that didn't help. Tossed them out and got a couple fresh ones, soaked them fully, and same deal. What the heck! I've heard of vape tongue, but from what I've read this is more a case of losing the taste of the juice entirely, not a bad taste across the board. The only one that still tastes good is my Siberian Winter (very strong menthol). I hadn't hit this juice in a while. Could it be just that I over did it on those particular flavors somehow? I'd been vaping pretty hard on them the past few days. Any insight would be appreciated.
