Check out spreadsheet below. Eddie is a recently diagnosed diabetic. On vets orders he was started on lantus 5 u once a day and vet had him in for spot glucose checks every 5 days or so. By the second week I bought a monitor, started home testing and took things from there. I finally started giving lantus twice a day this week, hoping it would help even out his numbers, he is always higher in the morning and before his dinner than after and the evening BG numbers have been lover even without a second dose of insulin. Today I though I was on the right track. BG was 113 this am, I gave him 1/2 a unit then when i got home he was 167, I fed him and 2 hours later he was 94 and I gave him another 1/2 u Going to check him again before I head to bed. Tested, 74 and Eddie is eating his bedtime meal. Is this just the usual action of lantus? Should I stay the course? Other details, he was switched over to wet low carb food around Jan 1. He gets just a little low carb dry food occasionally. He is a tad overweight, should be around 14 or 15 pounds and he was 20 at last trip to the vet. I have no scale to check his (or my) weight with. Eddie is about 10 years old. He is big, orange, loud and has the figure of a seal.
