I've been type 2 for about 3 yrs. I was prescribed metformin 1000mg 1 a day until January this Yr. I wasn't feeling right so booked in for blood test which showed my sugars weren't under control so they doubled my meds to 2000mg. One in the morn and one with my evening meal. Unfortunately they made me feel very sick and go to the toilet frequently. I had to have another check up 3 mths after the change in my dosage but this showed it was still not being controlled enough. Because of how I felt they lowered my metformin to 500mg and gave me a new tablet called empagliflozin 10mg once a day, to be increased to 25mg daily in 2 wks. However I feel like the dose is too low. My original symptoms are back. I get tired just walking upstairs. Any advice please?
