hi karen,
i want to second what serryn has told you. you won't have a good response as long as you are changing terra's dose around. you will continue to see wonky numbers and you won't be able to get terra regulated. i can't emphasize that enough - lantus likes consistency. it's just the way it works in cats. between dogs, cats & people with diabetes, cats are the hardest to regulate. you want to try to stay as close as possible to 12 hours apart on the shots (you've got about 15 minutes leeway without it affecting anything) and you want to hold the dose for at least 6 shots that are consecutive. of course if life happens and you can't do it in 12 hours, you just do what you need to do and regroup later.
if you post daily on one of the lantus forums - i know you've posted in both - but if you post, at least on the TR forum people watch out for newbies and will simply tell you when you need to change the dose. i'm sure that's true on the relaxed forum as well. we encourage newbies to edit the subject line of their first post of the day and ask for someone to give advice on the dose - then a person who feels comfortable reading terra's spreadsheet will look at it and give you suggestions to hold the dose or increase. when we increase it's almost always by .25units. a 50% increase is a lot and it causes even more bouncing - which you are seeing some of.
i saw you are contemplating starting over. i'd discourage you from doing that at this point. you've got some significantly high numbers, you're reporting some symptoms that are concerning and possibly from the BG being too high. i'd return to 1.5units tomorrow morning and then stay there for at least 6 consecutive shots.
it's an overwhelming thing to learn - i totally understand. don't feel badly about any of this - let's just help you get terra back on track! hang in there and the folks who are farther along the sugar dance than you are will help you learn.
regarding your question on food - at 7am i test punkin's BG, prep 1 can of fancy feast low-carb and get his insulin ready. when i put down the food bowl and his face starts sucking, i shoot the insulin in. 3 hours later i test his BG and give him 1/2 can. from that point until the next shot at 7pm, i give a very small snack when i test him. at 7pm i repeat the process from this morning.
i don't change any of that routine based upon numbers, except to test more often if it looks like he may be getting low. if a cat is sick and vomiting, then post and someone can help you discern if you should give the full dose or not.
just ask if you want to change the dose so we can give you the benefit of our expertise! :YMHUG:
it gets easier!!! truly. i would guess it will take a few days for terra to recover from all the changes, however. hang in there!!!
