Lovely blue AMPS....very encouraging! So far so good! Can you get some tests mid-cycle today? Also, try to get a before bed test every night if you can..many cats go lower at night.
Can you try to do a curve one day when you're home? You want to try to pin down his nadir if you can. That will help you figure out when he's likely to be lowest. Doses are adjusted by nadir, so you need to start looking at that.
