I have to say, I am definitely FOR the Keto-strips. I don't hold them up as the means all ends all, but they help me keep a check on myself. I do them before bed each night, and it really makes my day to see that I am in ketosis. I had one of my mom's slushies (sugar, iced tea, lemonade and booze - egads!) one night and sure enough I was certainly NOT in ketosis. It helps me watch myself. Just my opinion.
