Curious coincidence since cutting out sugar in tea: when I bought my new vape at the start of the year I was on the tail end of a really persistent chesty cough and couldn't be bothered to wait to try my new toy out.
Subsequently nearly every hit has been producing a coughing fit on exhalation.
Noticed in the last couple of days that's stopped completely - related? No idea.
Finding the milk aspect a little off-putting without sugar, might move over to green tea for the habitual brew

Sometimes always.
It's been a matcha heavy week along with a couple of rare cups of pepsi max last night so I should have dealt with the caffeine crash sooner but that trinity combo was, in fact, medicine.
Which makes me a doctor.
