Lori,
You don't have the data to shoot a number that low and know whether Tom will be safe or not without testing. Whenever someone shoots the lowest PS they have ever shot, we always suggest that they get a +1 and +2 at minimum....and then further testing as indicated by the intial tests. Knowing that you have a sleep disorder and are not able to stay up and test, the safest course of action was what Sienne suggested...to skip the shot. Tom's safety is the top concern. If you skip, you may lose some momentum, but you will know that he is safe.
Feeding while stalling is a problem....whether he drops or rises from food is not the issue. The issue is that the numbers you get after feeding are influenced by the food....so you can't tell if he is rising or dropping naturally. You fed, tested 20 minutes later and got a dropping number, then tested 40 minutes after that and got a rising number. Usually it takes longer than 20 minutes to see the effects of food, unless you are using karo, etc. which is absorbed more quickly. An hour is long enough to see food effect...so I'm *guessing* that Tom was probably dropping naturally and then the rise was a food spike. But the problem is that there's no way to be sure once you introduce food into the situation....so it's a guess, KWIM? That's why we tell you to not feed when you are stalling....so you can get a clear picture of what is going on. You don't want to shoot a food spike, because the food spike will wear off and the insulin onset will occur at about the same time...that could lead to a big drop.
I suspect that you are going to say, "But I shot a BCS dose, I was playing it safe!" Here's where you are still thinking PZI......you forgot about the shed. Many times when you shoot a reduced dose, you don't see the full effect of the reduction until the following cycle and/or cycles after that because the shed "makes up" for the missing insulin. Likewise with a fur shot...usually you see the full effect of the fur shot during the following cycles, not necessarily the cycle when you gave the fur shot, because of the shed.
I know you see people shooting low numbers, and you hear about "shooting low to stay low". We want you to get there, but first and foremost, we want to make sure that Tom is safe while you are getting there. You need to be able to monitor if you are going to shoot a lower number for the first time. Anyone without the necessary data would be told the same thing....you don't want to shoot a low number that is dropping or food influenced if you are not going to be able to monitor. It's not safe.
So glad that Tom is working his way to healing numbers... good luck!
