When you are in true ketosis you will notice a slight sweet taste in your mouth. For me it is usually first thing in the morning or after taking a drink of water. Personally, I think that it tastes a little like Splenda sweetener. (A very toned down version of it). Also, I get very warm at the same time every day when I'm in ketosis. Even when it's 50 degrees outside. My face gets flushed and my hands are very warm. To me, it's like a feverish feeling but without the chills or icky feeling. It's warm and fuzzy. LOL
