I think you will find that the reset time will vary with the person. Having smoked over 40yrs, only the strongest flavors come through for me. I get no taste

from the majority of e-juices.
Smell on the other hand, came back rather quickly.
I never knew how bad the world smelled. Must have changed the cats diet cause the cat box never smelled that bad before. Ash trays and smoker areas are becoming disgusting. Walking through malls is an experience. Really like walking through the fragrant candle aisles. Hmmm, might even be able to smell the flowers this spring.

I read the comment about how bad the world smells and it made me laugh - I actually snorted. I've been smoking almost as long as you have (I started smoking when I was 12, there - I admitted it). I've always had what
I believed to be an overly-acute sense of smell.
Interesting though, when I get honest and think about it, - the horrible smells that occasionally invade my senses have always been limited to being described as:
a) raw sewage
b) wet dog
c) swamp @$$ <--- ?? Seriously? I've actually described things that way - "Geez, it smells like swamp @$$ around here!!" As if I, or anyone else for that matter would ever have the instant ability or knowledge of what that really is or even smells like?

The reality is, I've only been able to discern that I smell something vaguely unpleasant, and 9 times out of 10, I am the only one! Everyone else will wrinkle up their noses, concentrate on the air for a second, give a slight eyebrow raise.... and say, "Oh, Remie's Phantom @$$ has returned", or "Watch out, Remie's phantom Wet Dog is loose again!".
So, it is perfectly normal, especially right now for me not to taste the "deliciousness" in the flavored e-juices. Some of them really smell "good". As far as flavor, the only thing that matters to me right now is mint/menthol, the stronger the better. It's probably because I can't taste anything else!
I am waiting to start noticing smoke on other people and in their cars. It was never an issue for me. I managed to quit during my pregnancies and during the random surgeries, hospital stays, had almost a year quit when I tried Chantix... but -I was raised by a smoker, so maybe it's just a familiar smell

I hope the smell starts to disgust me, honestly! I do not want to smoke cigarettes, not now, not nevah! I want my body cleansed, healed, and healthy.
As for salt - wow - I've spent a lifetime adding a little food to my salt! You guys are now telling me I'll taste food?

Thank goodness I've always had low blood pressure so salt hasn't been an issue.
So, in conclusion

Being a lifelong die-hard smoker, it may take my senses longer to regenerate, but I can expect some rapid changes.
Maybe the Phantom Wet Dog will finally go away for good.
