Anyone in the same boat?

My doctor prescribed me Metformin for my type two diabetes. And gradually increased the dosage over time. As of last year, I am on the MAX dosage of Metformin that a person supposedly can take in a day. Which is 2500 mg. I take 1000mg at breakfast. 500mg at lunch and another 1000mg at dinner. I personally feel like yes, it’s slightly helping but I feel like it won’t be good on my body in the long run. But who knows?!?!

I’ll take any advice or recommendations. Please.
