How bad is sugar?

hermiony

i know its bad, but i would like some help please.

I was having 5/6/7 cups of coffee/tea a day with 3-4 sweeteners every day, not to mention putting it in cereal,yoghurt and anything wanted sweet.
i couldnt just cut back as i was addicted so gave it up cold turkey and now i only have 1-3 cups a day and use one teaspoon of sugar in one or two of the cups i have, until i can wean myself off of the sweet taste and cut it out completely. but my question is, how bad are those 1-2 spoons of sugar? will it mess with my weight losing?
