look at the colors on your whole ss. The most frequent pink is at +4, and they are brief, then he's back up to red.
Typical nadir for prozinc is kind of extended, and occurs between +4 to +7.
It does seem to get more steady, and predictable, and later, after a few weeks.
With Cody nadir moved around a lot but was always lowest mid cycle and highest at preshot. Once we got up to a dose that was close, his nadir got later, and the duration got longer.
Once he's been on a dose for 3 days its wonderful to get several mid points so we can get a feel for what it does, and how long it lasts and whether its time to move up .2
Once you get up to a good dose it should last close to 12 hrs.
If preshots get too low, you back off the dose and the duration shrinks. Its a balancing act.
