I don’t use a TSlim yet so I currently manage my diabetes using a Medtronic pump and for the last 18 months a G5 Dexcom CGM.
We all have particular issues that cause us problems. I had a huge problem with meal spikes. I used to count carbs, pre-bolus, eat my meal and watch the spike go up to over 200 and maybe after 4 hours it comes down and maybe it doesn’t. It was very complex. Should I count only carbs, what about fast acting vs slow acting carbs, what about counting some portion of protein or fat as a carb equivalent, how long before my meal should I pre-bolus, etc. So I don’t do much of that anymore.
I figure if I ate a normal meal such as meat veg, a piece of bread or small potato maybe something for dessert, I would take 4 units of insulin. So this is what I do now.
For every meal I take 4 units. I eat only meat and veg for dinner despite taking 4 units. I watch my BG go up and then stabilize and then start coming down. When it comes down to about 110, I eat something else sometimes low carb ice cream, sometimes cottage cheese with chunks of pineapple, etc. So at 110 I eat my dessert, or anything with more carbs. In the meantime, my BG of 100 came down to 85 but when the add’l carbs kick I see it steady and then begin to rise. Sometimes it stops at about my target in which case I was successful and I wait until the next meal or go to bed. If I need to eat more, I do. If I need to give a small correction bolus, I do. But at least I avoided that big correction and anything else that could arise.
Think about what I have done. I know longer count carbs. I no longer wonder about glycemic index, I no longer worry about whether protein or fat will affect my BG, and I no longer worry if the bolus insulin is absorbed as expected. If not, I simply stop after the meat and veg and avoid a HUGE spike.
It really becomes quite simple especially with a CGM.
In effect I eat to match the duration of insulin (hopefully two or three times over 4 hours) and I avoid the spikes and everything else I just discussed. It works for me as my ave BG has come down to 107 whereas before I figured this out it averaged 160 because of meal spikes and lots more things.
Hope this helps. It helped me.
