I'm drinking less coffee and am really surprised. It is probably the most obvious - to me - change, other than the tastebuds are revived. I never had much of a hacker's cough - some in the morning... and that's gone, but the thing I've noticed the most is 'less coffee'. I've also not gained weight and thought I might. I love coffee too - starbucks columbian (actually any full bodied columbian). And I've never limited my intake.
I'm at the EXACT same place.
Use to do up 2 starbucks in the morning and 2 after lunch plus a full pot when I got home.
Now, I barely finish 2 during the work day and maybe have A cup after dinner - with my evening vape
WEIRD
But I am drinking more water than I use to.
