I suffer from chronic heartburn, so I am no stranger to antacids. When I was browsing my local drugstore I happened upon TUMS Smoothies and decided to give them a try. This particular type of TUMS seems to get the job done, it is equally effictive as Mylanta chews as far as speed and duration of relief. It takes about a half hour for me to feel the effects and I never need to take them again for the same episode. The thing that sets this brand apart is it's texture. When I chew the tablets, they practically dissolve on the tongue with as little of a chalky texture as antacids allow for. As an extension of this, there is never a gritty residue left after I take it. The flavors are also preferable to other brands, partially because the texture is improved and partially because they are more mild, while still providing enough taste and sweetness to trick your mind into thinking you are having a treat, if only for a second.
