Hello, It has been one week since I removed dry food from Nathan's diet. And he has been on 0.5u dose for a few days. His AMPS levels are always high enough to shoot him the full dose, but his PMPS levels are usually between 150-200. So I have to either skip the shot or give him a token dose. Today his PMPS was 88, the first time <100 as pre-shot number. Then we re-tested immediately, got another reading 107. I have decided to skip his PM shot due to this low number. However, do I need to reduce another 0.25u from tomorrow morning, since I got a 88 (but then I got 107?)?
