I don’t have sugar in my coffee either. If I can avoid it.
I have it with milk and that slight sweetness in the milk is probably enough.
I think the better way to deal with this is to reduce the coffee intake. If you are having , say an X number of cups. Reduce gradually.
Also reduce the volume. My coffee with milk is a standard 100ml cup in the morning. I don’t know how much you are having.
I think @Bekloppt isn’t doing it for caffeine, so your advice of reduction of intake doesn’t help, unless you’re referring to reducing portion sizes in general for the associated reduction in sugar.
But there is some wisdom to be had from that – @Bekloppt you could try reducing the sugar in your coffee day by day…
I’ve been a black coffee only drinker since the early 1990s. The only downside is that I have to have my teeth cleaned with a Dremmel and pressure washer every 6 months.
Have you tried using a sweetner instead?
I changed to sweeteners, not say how many the wife suggests I need 
I removed milk from my diet completely, which meant starting to drink coffee black… Decided to remove a sugar craving/intake at the same time. Never thought I could make the transition after the first few days of it, until I decided to lessen the ‘bitter toxic shock impact’, by never attempting to drink it without the aid of ‘dunking’ a Digestive biscuit, or ten…!
Weaned myself off the biscuits after a week or so, replaced them with a Jacob cracker/s, some just buttered lightly, some with just a smear of jam… Again, weaned myself of them as a sweetener aid, when I could take gulps of the coffee without it leaving a horrible taste in my mouth…
A few weeks after abandoning milk or sugar in the coffee, could not believe I hadn’t opted to do this years ago - The way I look at it now… milk or sugar in coffee, is for wimps :0)
Trying to do the same with a cup/mug of tea was impossible though… that attempt at a transition beat me hands down…!
Sat waiting in the van hire office. Bloke at the counter being served.
“Can we have an emergency contact number please, not yourself”
“Yes (number)”
“And who’s that please”
“My partner’s”
At this point I sort of knew what was coming.
“What’s her name?”
Ah…….
You are an inspiration sir.
:0)
And then you get the smallest known measure of time, the Ohnosecond, which occurs immediately after the maximum dunking time is exceeded and you end up with a piece of broken bickie and a layer of sludge at the bottom of the teacup.
That is a public hazard! All those times are too long. You’d end up with a soggy mess in the bottom of your mug.
In fairness, they were rationed in those days.
I haven’t had milk in coffee for about 6 months. I might be mildly lactose intolerant, I don’t know, but I was noticing a coating inside my mouth and it is much better since chopping out milk. I have one good cup of black coffee in the morning, and then I will drink green tea in the afternoon at work. No milk or sugar in anything and feeling a bit better for it.
I dropped sugar in tea and coffee as a teenager. As a sweet treat from time to time, I will eat a slice of dried mango. Natural sugar and fiber too, I only discovered it fairly recently but I’m sure it is much more common in India and the far east.
Oat milk. Sweeter than normal milk
Doctors prescribed a sweetener as the alternative for sugar when my mother was diagnosed with diabetes. Surely you can find that in Australia/Germany/UK.
Lies, a rich tea goes all soggy just looking at a cuppa
Just need a big spoon with holes in it, only took me 58 years to work this out rather than using a normal tablespoon, that’s when I realised I’d reached genius level in my life.
havent had sugar in coffee for decades… its amazing how quick you adjust…only took me about a week…if i accidentally have some now its disgusting…sugar in tea is the devils work
Secret with dipping Rich Tea… you need to inspect for fracture lines within the biscuit before dunking… Spot them you have a chance of breaking them in two first, miss the fault line, say goodbye to half the biscuit until you reach the dregs :0)
Top notch content 
Yes there is a true art to biscuit dunking.
Loved this Peter Kay sketch had me in tears when i 1st watched it as it is true to life.
