Ketostiks are not known for their accuracy. You get different readings depending on how much water you have been drinking (among other things).
I would suggest you start a journal - it is an excellent way to record your food, moods and progress. Plus, it will cause you to interact with other members. Ditch the Cremora - go for the heavy cream. If you are on induction, limit your cheese to a couple of ounces a day. Some people will react to caffeine, sugar alcohols (like those in the Advantage Bar) and asperatame ( in the diet soda). Personally, none of these things effect me in the least.
