A question first, what is your name? I'd like to call you more than Eddie's Mom. ;-)
A suggestion, perhaps it would be easier if you created a second spreadsheet for numbers this year. That way other members could look at correct US numbers and help with suggestions. In case you've forgotten how to do this, here are the
instructions. I found it easier to create new spreadsheets for each of year for Neko. There aren't many numbers in Eddie's SS for this year, so it should be an easy cut and paste.
I suspect that Eddie is doing a bit of bouncing. His body (and liver) have gotten used to slightly higher numbers so is reacting to the low numbers. There is a good description of bounces in the second post
here. For example, last night you started at 14.8 (266) and at +3 he was at 3.8 (68). That is a very fast drop. Fast drops can also cause bounces. But more importantly, I would have gotten a +4 test. It is highly possible that Eddie dropped below 50 (2.8) last night and in fact needs a reduction.
Altering your feeding schedule might help flatten out Eddie's numbers. If I understand correctly, shot time is 7AM and 7PM but you are feeding at 7AM, 5PM (+10) and 10PM (PM +3). It's best to feed at least part of the meal at shot time so there is food on board when the insulin onsets. That could explain some of the fast drops you are seeing in the evening. Also, it's best to not feed much in the last half of the cycle when the insulin is waning and to not feed anything for 2 hours before shot time. The 5PM feeding is probably raising his PMPS numbers. Any chance of moving to 4 meals, say at shot time and 1 or 2 hours later for each cycle? I have a timed feeder that helps me with the after shot meals.
