Tonight, Tut had his lowest ever BG prior to the evening meal/Lanutus shot, of 235. Pre-shot read has consistently been above 300, since we started insulin 11/11. He was in high 300s at vets prior to that. I don't have a full chart yet. I've been testing at various times per day, with the intention of putting a curve together. Our vet initially recommended 3 Units, and I cut that back per 'go slow' recommendations here, so haven't been too worried about getting too low. His lowest Ever (anytime tested) previously was 167 (6 hours after his am shot today.) Seems like this is probably good. But, I'm wondering if I should be worried about the extent of the drop. He ate more than usual today. He's gained 1 lb. since 11/11 (after losing 4 over the last few months) (was 17; now 14); behavior has been much improved; seems happy. I see I didn't get a read last night. Yesterday am, preshot he was 334. I'd appreciate any input. Should I sleep?
