Pumpers, do you see a difference in how you dose?

Diabetic Educators, people who do not listen, people who do not actively try to make their situation better, people who think I am in their textbook, people who think I am a standard T1D.
I have been on an insulin pump since 2000. I was on a Medtronic pump until 2015 when I switched to a Tandem Pump. I began using my Dexcom CGM in 2013. I was diagnosed T1D at 1 month old, after constant crying, wetting, sweating and vomiting. I grew up just knowing there was a better way to exist with my condition, specifically, more efficient ways of testing my sugars and more efficient ways to take insulin. I have those. The really cool thing is still on the horizon, an external pancreas! My CGM and pump working together!

One thing that has kind of happened but not as I think it should, super fast acting insulin. I understand why we are trying to create extremely long acting insulins, I will never go back onto one of them. Everyone may disagree, I feel I have more control over my glucose with faster acting insulin. Plus, long insulins are not used in pumps that I am aware of. Through 51 years of use of foreign insulin, I developed Diabetic Gasteroparesis, DGP, or, digestive paralysis. It can take up to 3 days for me to digest anything. Since I am never sure when the carbs are going to hit, it is very difficult to time my insulin doses ahead of time, thus, I would like a very fast insulin that reacts as soon as it is in my body. I only take Novolog. I have very bad reactions to Humalog. I noticed when I do a carb dose and a corrective dose at the same time, my sugar starts dropping within 5 minutes. When I only carb dose, it takes 45 minutes + to react. And no, I am not exaggerating nor am I embellishing. I have repeatedly documented this with the CGM. If my sugar is rising, I now use my corrective, basal to deliver my insulin.

Has any other pumper noticed this? I have asked everyone at Dexcom, my husband is a Software Engineer there. I have asked everyone I can contact at Tandem. Everyone tells me this makes no sense. I know it does not, but it works for me in this manner.
 
@rstonepal As is said by many in the online community, "Your Diabetes May Vary".... Looks as though you have some interesting characteristics going on there.

I notice that when I take corrective doses at different times of the day, the onset time of the insulin varies, but I also note that time to action varies according to dose size for some reason, so I can understand your frustration!

As your husband is a software engineer, have you thought about doing something with the OpenAPS project? There are people that have built closed loop APs "in their bedrooms". It certainly looks interesting.
 
Yes! Me!

I wouldn't say as quickly as 5 minutes, but not so far after...maybe 10? But yes, definitely noticed that too!
