Capital NO! I don't make use of sugar whenever I am drinking tea. Funny enough, I used to when I was much younger and ignorant about the health implications of eating white sugar. Back then I can't drink tea without adding sugar to it. And if tea is made and sugar is not in it I can't drink it.
Suddenly, all that sugar addiction changed when I grew up. The change was brought about when I gained the knowledge that sugar are not healthy for grown ups, especially if consumed in large quantity and done frequently. Sugar might be healthy for children, because of how their metabolism is still very fast in terms of its function, unlike that of adults, which slows down as they age.
Ideally, drinking tea with sugar is not needed, because those beverages already contain certain amount of sugar in them. Additionally, most food we eat already have sugar in them, too.
