dont know what it is, the placement of the place where i keep the
teas, water boiler, the countertop, the sink, stress, no new teas,
winter? ...dont know, but
i am drinking too much cola again, arrrrgh.... tried sweetening the
black teas,,,
tried the usual 'cure' of doing a tea binge day...but i just cant seem
to get back to my routine...

Sometimes nothing quenches a thirst/sugar need like a cola. The reason
you're drinking too much is that you buy the stuff in the first place.
Don't buy it, and you won't have a problem.
