Suddenly needing more insulin at random times, no end in sight

Hello!

For most of my adult diabetic life (diagnosed at 8, 24 now) I have hovered around 28-33 units of Lantus/basal with my type 1 diabetes. However, since November of last year my body has been suddenly needing more insulin at random times. I am now all the way up to 52 units and I don’t see an end in sight with the changes.

I don’t think I have an infection, my weight hasn’t changed, neither has my activity level. I feel like I’m eating less now than I was before because I keep resting in the low 200s until I have to up my dosage again and feel too high to eat. Then, the new dosage works for a few days or even weeks, and I then I have to adjust again. I have tried contacting my doctor, but they aren’t much help.

I feel so hopeless and defeated right now. I’m doing everything I should on my end and I’ve adjusted my correction and carb rates with my humalog too.

One thing to note is that I was forced onto humalog from Novolog by my insurance this past August, but like I said, I didn’t have issues until November.

Has anyone else experienced something like this or have ideas I could look into? Could it be insulin resistance? Is this normal?
