I was about to say something to that effect, but I didn't want to be too pushy. But, I think I'm going to anyway. ;-)
If you're getting at least three tests a day (the two preshots and a nadir), then you can do TR. I managed to do it working two jobs and going to grad school, so I'm not someone who was home all the time to test. I would always recommend newbies start with TR first, and then go to something more relaxed if it's just impossible for TR to work for them. That's because the 86% remission rate with Lantus is only associated with TR, so it offers you the best chance of getting to remission. But there's a window on remission and TR, so the sooner you start it, the better your chances.
To give you an idea of how I managed it, here's what I did. Bandit's shots were at 7am and 7pm, and his nadirs were typically 6hrs after each shot (1pm/1am). I tested and gave him his morning shot and food, and then I had to leave for work for nearly 12 hours (I have an hr commute both ways). So I set the autofeeder with frozen food and set it to go off at his nadir (1pm) so that he had food available if he dropped a little low. I got home just before 7pm and tested and gave him his PM shot. Then I got a test before bed (+2-+4), and I set an alarm to get up at 1am and get his nadir test every day (+6) and went right back to sleep. That seems like a pain, but after a week or two I adjusted and it was fine. On the weekends when I was home to test, I would do a curve in his AM cycle and get some extra tests in when I could.
It is a little bit more work, but it actually SAVES you a lot of work and stress in the long run. A cat in remission is far easier to care for than a cat on insulin, and it's the healthiest place for a diabetic cat to be, so it's win/win for both of you. If there's no secondary health condition that might throw off his BG, it's very likely your cat will reach remission with TR.
