Hi Lydia,
I'm an old ProZinc user, we started out on it when Mr Tinkles was diagnosed, when the insulin was pretty new. We switched to Lantus after 3 months because he had a chronic URI and the big swings he was seeing with PZ were not allowing him to clear the infection. After 15 months on Lantus, he went OTJ. I just wanted to give you a brief background so you know where I'm coming from....feel free to take a look at our SS, the ProZinc data is on the second sheet. Probably nobody who is here in PZI now remembers us from then, but PZI was our first home on FDMB.
When we arrived in PZI, we were fortunate enough to have two members who had recently successfully used ProZinc on a TID schedule....Michelle & Prudence, and Hope and Aria. They both had only used it for about a month, and then they returned to a BID schedule.....they could no longer shoot TID, their kitties were well regulated and their duration was more typical of PZ at that point. I will link their SSs below, I think you will find them very useful...they both kept good notes on the SS to explain their thought process. Both kitties ultimately went OTJ. Unfortunately, Prudence is GA. :cry: I don't think either of them have posted in a long time. I personally have never used a TID dosing schedule, but both Michelle and Hope (among others!) were invaluable to me during the start of our journey. I would suggest doing a search in the PZI forum for some of their posts about TID dosing...the more info you have, the better!
You will notice that they were both pretty aggressive about monitoring and shooting as soon as kitty started to zoom up, but they also were careful about waiting for significant/clear rise when necessary. Their TID schedule was not always every 8 hours because they let the numbers be their guide as to when to shoot...it makes for a crazy schedule, but in their cases, it was relatively short term and it had a big payoff. They also found more success with relatively consistent dosing VS sliding scale....that was also my personal experience with ProZinc. I think you are wise to be pretty aggressive with Sid because of his DKA history, as long as you can do the necessary monitoring. TID is not easy on the bean!

Hope and Aria's TID SS
Hope and Aria's BID SS
Another thing I would like to mention because I haven't seen anyone address it....you are giving Sid fluids, and it looks like sometimes the timing could be adding momentum to his drops. I don't have direct experience with fluids, but I do know that it can cause numbers to drop. You might want to adjust your schedule to administer fluids after nadir.
I think the feeding schedule is up to you, but in general, smaller more frequent meals help keep numbers more even. I would keep notes about feeding (along with meds, fluids, etc) on the SS, it will help you see how it affects the cycles. ECID, you will need to see what works for you and Sid.
You're a good bean, Lydia, Sid is lucky to have you. :YMHUG: I wish you both the very best of luck with ProZinc TID, I do think it can be a very effective strategy when used properly. Please let me know if there's anything I can do to help.
