I just went through the same thing. For 3 days my taste buds where 99% out of order. I couldn't tell the difference between boba's, gorilla juice, rafilicious or hype.
During those few days I did look at a old pack of cigs & the thought crossed my mind, maybe I can taste those. I just want to taste! Started unflavorabley vaping & convinced myself I know I wouldn't be able to taste those either, so what's the point.
Stick in there!
Oh, fell free to use my made up word (unflavorabley).
I guess it wasn't the cartos after all.
Today, I just got my 5v USB passthrough from VaporKings, filled a brand new carto with coffee and let it settle for 1/2 hour, drank lots of water, sucked on a menthol cough drop (since I didn't have any menthol flavored liquid) AND STILL NOTHING (but a whole LOT of vapor). No taste or sense of smell from the vapor at all except when I inhale through my nose. Even the formerly strong cinnamon flavor in Rob's Blackjack from Blue Mist tastes like a 3 day old piece of used gum.
I read that this can be caused by zinc deficiency and so I started taking a multivitamin with zinc today.
I expected to not taste well when I started, but not 5 weeks after quitting analogs. Fortunately, I'm not worried about returning to analogs b/c the vaping still satisfies the nicotine cravings.
