Hi Debbie and welcome. Giving up sugar is excellent advice, if you can.
Unfortunately I love espresso coffee, and while others can & do drink it without sugar, I can't:
I need two cubes of sugar, each of 4 grams; cubes/lumps because they're easier for precise control.
However, I limit myself to one espresso a day, morning usually.
If I feel like another coffee, mid-morning or later, I'll have a cappuccino, with just one cube sugar.
Whenever I've given up sugar in coffee, even in instant coffee, I end up giving up coffee. Even taken with milk or cream.
Once I persevered without sugar in coffee and tea for 6 weeks, honestly, without sugar it tasted as disgusting on the 42nd day as it did on the first day. Yet people here get used to no sugar in a few days: guess we're all different! Or I'm particularly addicted.
As for tea, I can drink it without sugar, but don't like it; it's no coincidence I've almost given up tea altogether.
Occasionally I worry about putting sugar in my espresso and instead use xylitol for a few days; I find xylitol acceptable while ALL other sweeteners are nauseating (especially "fashionable" stevia) and more disgusting than espresso without sugar.
But I suspect overuse of xylitol can lead to diarrhoea. Metformin does too, I tried the slow/prolonged release version, my fasting blood glucose level crept up and the diarrhoea reduced but didn't disappear, so I returned to ordinary Metformin.
Obviously sugar is not to be recommended to diabetics, and I'm not doing that, but I find rice, bread, potato, pasta (all the usual other suspects) and even whey protein spikes my blood glucose more than sugar.
FYI, I've been type 2 for 10 years, and on Metformin 500mg for 7 years.
Sorry, this has turned out longer than intended, best wishes, Aldo.
