Good afternoon Patty -
I think it was me that suggested TID. I would definitely hope that Sue & Robin & Carl continue to give you some more guidance before you get to the point of trying TID. Grayson didn't bounce much when we were on ProZinc, so I don't have the experience to advise you on pulling out of a bounce. I know that most bouncing kitties need to hold the dose for longer before they increase. If that's the issue, then you may not need to think about TID. The kitty will balance out over time.
If, however, you guys conclude that that's the direction you might want to go, I would ask you to look at your schedule and see if it would even be possible. I work 5 minutes from home, so I could slip out and be back at work in 15 minutes. Most people can't do that. Shooting every 8 hours is much more demanding on your life than BID. If you work full time and commute an hour each way, you probably won't be able to do it. Also, it may mean getting up at 2 am or 4 am to shoot, depending on your hours. Despite living close, I did not function well when I couldn't get a solid block of sleep during the night. It's also a LOT to ask of your petsitter, if you don't have someone helping you (I live by myself) and you have to go away.
All that being said, you're seeing substantial drops on a normal dose. Most of us that have done TID were also shooting 3-6 units BID. It was easier to divide the total insulin (for 24 hours) into 3 doses when you're looking at larger numbers. ie: 6u x 2=12u per 24 hrs. 12u divided by 3 doses =4u. You can use the other needles and the conversion chart, as was mentioned, but you have to be REALLY careful. Thank God Grayson is insulin resistant, or I would've killed him by shooting the correct dose on the wrong needle - essentially 2.5x what his dose should've been at the time!
Perhaps you could do a test drive... when you'll be around... and do a curve. When he starts that climb, if it's at or just past +8, shoot 1/3 of your total daily dose. This dance is a lot abotu trial and error. That's why we encourage people to get lots of tests in, so you can see patterns and make informed decisions.
Fingers crossed that all goes well and you can get away from those blacks & reds.
