I'm new here and have not yet got everything together for the home testing and was planning on doing this tomorrow. In the meantime I'm wondering how normal or abnormal it is for my cat who is on 2u of Prozinc twice a day to be so lethargic late in the day when he is very alert and active the first half of the day? I know it's hard to tell yet because I can't test his BG right now but I'm wondering if anyone has any tips or hints at this point? Is this a sign of him not being regulated yet? He's been on the Prozinc for about 8 days now.
