I can feel the envy of the USA members when they read about the price of insulin in Canada! And no prescription needed! I'm lucky: I live near the border and can just go over to buy Lev. at the Shoppers Drug Mart in Cornwall, ON. No questions asked. I was invited to join Shopper's Optimum discount program, and when I told them I lived in the US, they said, no problem, they had just issued a card to a New Zealander!
I now have a wonderful vet who leaves Rusty's diabetes treatment up to me. But that was not always the case. I shot my first diabetic cat, Stu, "blind" (no testing!) for 4 years (but he was on one of the older, in-and-out insulins, not a "depot" insulin like Lantus). When Stu was switched to Lantus because the other insulin had been discontinued, my vet at the time treated it as if it were the older type of insulin. Stu's dose was raised by 1 or 2 units every week until he was up to 7 Units twice a day and crashed. That's when I found the FDMB and learned how to test. This wonderful group of people saved Stu's life.
I see that syringes cost much more in Canada than in the US! (trade-off for the insulin?) I also see that you are using Monoject syringes. You should be aware that Monojects--if they are not perfect--have a problem that could cause you to give more insulin than you think you are. Several years ago I addressed this problem in a Google Doc. Here is a link.
