We definitely know exactly how you feel/felt! I was terrified every day in the beginning that Simon would hypo, especially since in the early days, he would hit his lowest reading/nadir after only 2 or 3 hours and he would drop from like 300 to 100 in that time! Scary indeed. But, the more data you collect, the more confident you will become in dosing and knowing how your cat will generally react to each dose. That is why home testing and mid-cycle really helps a lot!
Happy New Year and best to you and Patches!
