I dont know how people do it, every sugar alternatives I've tried taste like ass: sucralose, aspartame, acesulfame potassium, saccharin, all of them are fucking disgusting.
I'd say sucralose is the most pernicious, I've bought things not labeled as no sugar(Asian countries LOVE using it in random shit) and as soon as that aftertaste hits I gag.
It’s best to just change your palette so it doesn’t need sugary tastes anyway. If you don’t want sugar substitutes, just change your diet so your body doesn’t expect sweet things at all. That’s a great move.
Everyone looks at me strangely when I ask for 0% sugar in my bubble tea. The pearls already have sugar in them, and when your palette changes, you can taste the tea and milk so much clearer rather than having all of that covered up by the taste of sugar.
Tbh attempting to replace sugar with "sugar alternatives" is part of the problem. The other part of the problem is that commercial goods are sold with a fuckton of super sugar (high fructose corn syrup et al.) added to them which is completely unnecessary. If you just try to get your sugar from natural sources and try to eat some fiber with it (whole fruit is perfect for this) you're on the right track.
The short version is simply: don't drink your sweets
