I've been treating my guy for 6 weeks on PZI gradually increasing dosage at my Vets advice and testing now I've done 2 curves in the past week at the 4u level! Vet wants to go to 5u and do another curve! I've done 2 curves in the past week and am doing a mid cycle test when I can. His pre shot numbers are still very high but I seem to be seeing inconsistent numbers mid cycle and his 2 curves were conflicting. Vet wants to hold off on food during a curve cycle unless I get a hypo number during the curve cycle. Is it preferable to only feed ate the shot times in this case to see the numbers for 12 hours without the effect of food on the 2 hr intervals? Advice?
