I dont mean to stress you out, Pam. I know you are doing the best you can, and I am sure Larry appreciates it. But his spreadsheet, in my opinion, makes me wonder if he might be going lower on his PM cycle. What I am trying to figure out is if he is having a daily bounce due to low number at night (which would mean too much insulin, possibly) or if he is not getting enough, which is why we dont see a lot of result in the day time. They only way to know this is by getting nighttime data.
Again. My opinion only. Its your cat. And others may have other thoughts.
