i only drink water and most of my meals are homemade. i never add sugar to my tea or drink those high calorie sugary coffee drinks (hate coffee only had it once and it was awful) maybe it could be placebo? confidence and security have a factor for alot of people's stutter so i think maybe it's something along the lines of that? maybe stutters work differently for different people, just the same way depression does and how some medicines work and others don't though i am happy that it is giving you results ^_^
