After diagnosis Vet said levels were above 400 and to give 1 UNIT of ProZinc twice daily. Not sure why I wasn't given any info to test at home but after a few days of seeing my Lily look so tired after an injection and a meal I needed to know how her body was reacting. First test 2 hrs after a meal was 71. The next day she didn't eat much so I made the choice to only give .5 UNITS. 12 hrs later prior to eating her BG was 174 so I skipped a dose. 12 hrs later prior to eating her BG is 154 accept it seems as a result of skipping the dose entirely she vomited which had not happened in 6 days. I chose to give her .5 UNITS. I was concerned so I stopped at home to check on her and was able to get a BG and it was 66 6 hours later. This evening I checked now 12 hours since her breakfast meal 7 hours since the mid day test and it was 124. I am a bit confused and concerned I risk hurting her with too much.
