With the blues nadirs it’s not time to increase yet. Let’s see how he does today and tomorrow. While I know you are supposed to do a curve before deciding, if you do spot checks and catch the nadirs it’s even better in my opinion. Are you away from home after +4 during the day? If you can grab a +5-7 you will have enough info to decide dosing. I suspect he’s not going much lower but it would be good to have a test to confirm. If possible before Sunday a dosing decision might be able to be made after 7 days.
That’s great you have the dental scheduled as that could really help.
The more time he spends in blue the less severe the bounces will be. I don’t imagine it feels great but kind of like us coming down from a sugar high although I don’t feel at all strange then so who knows.
