I didn't realize the alk swing during the day (lights on) until I get myself a trident back in 2019. I cranked that baby up to 12 tests a day, sometimes more via manual click, for the first week or so. I've used CalRX almost from the beginning. To counter the swings, I would dose (using Neptune DOS) at the time when the alk uptake is at the highest (usually between 6-9pm). I used EHV but switched to Fritz recently.. same thing I guess.. anyone else is using Fritz?
I only dose alk. Calcium level never really changed throughout the day.
