while there are sites out there that do promote shooting lantus 3 times a day, in my own opinion, it's quite risky. i want to say but i'd have to re-read to make sure, even those sites, if one shoots lantus 3 times a day, say that you actually have to test even more so you get a better feel for the insulin reaction and to make sure kitty is safe because of issues like Gayle mentioned. if you aren't home most of the day or can't run home for checks thru the day, i'd say forget about trying a TID schedule with lantus.
with that in mind, i use lantus and thru the week i never shoot on a 12 hour schedule. work doesn't allow for it. while it may not be ideal, my cat and now my foster cat, seem to do pretty well with it and i've never had any complications due to it.
thru the week i shoot my evening shots as close as 12.5 hours one day to as much as 13 or 14 hours some days if need be. of course that makes the next shot alot less than 12 hours apart but it can work. you have to learn things like when it's safer to skip a shot because the next one is coming too close or perhaps reducing the dose a little to be able to shoot again the next morning etc.....the data you can collect in the evenings, or on the weekends and holidays, will help you with that. i will say that if your big goal is remission as quick as possible, (which personally i don't think should be the goal) this kind of schedule can and most likely will slow that down some.
