I dream of cutting out sugar - but it would ruin most coffees for me! I measure my sugar to coffee ratios in seconds poured. I like my sugar with coffee and cream!
This is at least how I (accidentally) ended up switching to black coffee. Ymmv.
Give it a try maybe, you'll find that a lot of coffee has really rich flavour that you're burying under the sweet sugar.
I’ll benchmark my current consumption on a scale. Then I’ll make a spreadsheet that reduces it over a period of two weeks gradually, until hitting zero.
You can adjust the duration to a month or whatever you feel comfortable with.
If you get your tea from a grocery store, chances are you're getting the lowest grade of tea (tea dust).
