Hello Vivaldi and his (human) bean!
Any comments on Vivaldi Spreadsheet will be welcome.
Well, .. he is high...
Perhaps your vet didn't mention that Lantus is the "depot" style, a cumulative potency insulin?
It mean you are only going to see good results if you handle it as such: keep the doses 12 hours apart + take tests at "strategic" hours and do not feel free re:changing the dose as you have felt doing it with Caniunsulin - consistency and method are the key to use the fullest of long lasting Lantus.
I do not mean to criticize, or anything.!
Have you looked at a Sticky Note at the top of the Forum?
Check out one method of dosing - SLGL and another one, a protocol - "TR" - see which one might be best for your situation and post with any questions.
Your spreadsheet at the time shows that a lot of changes were maid simultaneously - the SIGNIFICANT dose change, dose skips, ets. - to be accurate in the current reading of things. Perhaps someone smarter can have a pick and to comment better.
Unless he dispays sighs of ill health, pain, nausea, etc - keep the dose and add some more night time tests. It's sucks. But it'll serve you well in the future. I use alarm on my cell.
