Zero calorie sweeteners are so heavily advertised that it's surprising that you have missed noticing them. There are plenty of brands that are available in the market. These include Equal, Natural, Splenda, Sugar Free. Try them out but in moderation. There are some negatives about having zero calorie sweeteners and their long time impact is yet to be assessed. Maybe you could replace the sugar in your tea or coffee with them. But don't attempt desserts made with artificial sweeteners. Instead of going in for the artificial stuff, why not try and skip desserts and sweets completely. That might be the better alternative.
