I am eating sugar-free tablets with tea/coffe is their any side effect?
are you DRINKING tea or coffee with sugar free tablets or EATING it with tea or coffee-if former then answer is a big NO if latter then it is unheard of
they are chemicals...not natural
tablets of what?
You are better off to use a little bit of sugar (not spoonfuls) than any "chemical" replacements.
What's in those tablets? We know there is no sugar. But we don't know what's in them.
