Yes, I think you may be able to solve your issue with fast acting insulin. Doctors are trained to start T2’s on slow acting and it took me 20 years and a CGM to convince my endo that slow acting Levemir/Lantus (Long acting) is the invention of the devil for diabetics in my situation which is similar to yours. The pros of doing Humalog (fast acting) is that it is non-addictive so you can stop anytime if it does not work for you. You can use it at will, only when needed and it will allow you a total range of foods. So, if you want a slice of pizza at your daughter’s birthday, no problem just dial in 6 or so units 15-20 minutes before the pizza. Cake and ice cream, no problem just dial in 18 or so units 15-20 minutes before eating. What is really nice with fast acting is that it is mostly gone from the system about 2 1/4 hours after taking it and virtually totally gone within 8 hours. So, if you sin a little and use it at lunch, it will be out of system before bedtime, avoiding a possible nighttime low. A little trickier to dose properly if you eat dinner. What I think you will find is that as long as you pre-bolus (take your insulin before your food kicks in which is usually about 15-20 minutes) you will find that your BG stays totally flat-lined and then most likely you will still be flat-lined and not go low an hour later. You just need to figure out proper dose for whatever you eat (your insulin to carb ratio I:C) and you learn that pretty fast.
The cons are now that you can eat anything you eat more variety of foods and it is such a pleasure that you need to watch weight gain, which can be curbed by eating more fats which will kill your appetite but also affect your cholesterol. I am battling that now to reduce and hopefully eliminate my statin use. Another con is that as we get older, rigorous daily exercise is not so attractive. It is too cold or rainy today etc. and so easy to just take a few units of fast acting at mealtime and BG remains stable. I had needle phobia and originally told endo I could never take a needle. She said no worse than a mosquito bite and she was right and it took about 3 days to get used to injections.
Bottom line is that I would ask doctor to prescribe 1 box of fast acting Humalog Pens and give it a try. You have nothing to lose as you can drink OJ or eat candies if you go low at first so there is no risk there and you have everything to gain. Like everything else in diabetes, one baby step at a time and you will find what works. If you want to talk about this more over the phone, just PM me.
