Okay so I've been trying to figure this out for a while now. I am wondering if this may be what is spiking my bg at night. I eat all of my carbs by lunchtime, my blood sugars early in the day are pretty good (80-120) but because my blood sugar is so bad at dinner and nighttime I only eat 5g carbs of veggies and protein for dinner but after dinner my bg is about 140 after exercising 10-20 minutes and then when I check before bed it has increased! Usually about 150-185 and it is sooo frustrating I cannot figure it out! I have been thinking maybe it is my fat and protein I have eaten during the day digesting late...or maybe I just have my highest blood sugar at night... I would love to figure this out or else I think I may need to go on Metformin at nighttime. Any idea why my numbers would be so much worse at night? How long does it take fat and protein to digest and how much does fat and protein increase blood sugar?
