I use artificial sweeteners all the time. Have not tried Steevia yet which is supposed to be better because it is natural. although there is no proof yet that its completely safe either. " Stevia may interact with anti-fungals, anti-inflammatories, anti-microbials, anti-cancer drugs, anti-virals, appetite suppressants, calcium channel blockers, cholesterol-lowering drugs, drugs that increase urination, fertility agents and other medications. People should talk with their doctor before deciding to take stevia in large amounts".
