Welcome to you and Vivaldi. I love his name.
Regardless of following SLGS or TR any time you get a lime green number (below 50 on a human meter), you would reduce the next dose by .25 and further doses would be that same reduced amount. So your next dose should be 2 units and you would keep that dose until Vivaldi earns another reduction by going below 50.
Additionally, if he goes too low, you need to give him some higher carb food or honey to get his number back up over 50. We usually recommend testing 20 minutes or so after giving the sugar or high carb food to see if the numbers are coming up, if they are not, give more sugar and test again in 20 more minutes. In order to make sure Vivaldi is safe, you want to know that he is staying above 50 on his own 2 hours after your last sugar/high carb intervention. Sugars can bring numbers up quickly, but can wear off very quickly also.
How was he acting with those numbers in the 30s and 40s? Any unusual behavior or symptoms?
It looks like Lantus was a good choice to switch to and Vivaldi is responding well, you just have to keep him safe when he goes below 50 and take the reductions when that happens. Post here a little more often and review the stickies to familiarize yourself further with the dosing methods we use. If something doesn’t make sense or is confusing, ask all the questions you need to. There are so many knowledgeable people here willing to help.
