Do you trust keto sticks?

... Because mine have been trying to tell me that I've been in ketosis since the first day? I am being strict-ish, but thought it would take longer? I’m four days in and not had any keto flu either? Is this usual? Thanks

I'm on my 3rd day. I am definitely in ketosis. My daughter told me my breath smelt awful this morning. I've not had keto flu but I had to go to sleep very early last night. From memory it gets better around 7 day mark.
