how much it should show to know i am doing ok. i just did one and in 15 sec it turn to small 1.5, +. this is the third level of the scale of the ones i got. i am sorry if this sounds silly, i have never ever tried this before. i got some cheese, sliced cheddar. 4 days i didn`t eat any diary but it says 100 g contain less than 0.1 g carbs. so it should be ok if i eat in moderation, or not?
