Hello doctor,

My FBS used to be around 100-115 while on Metformin 500 mg twice daily (diabetic and PCOS). Recently I have been tired, and feeling hot in the nights, getting night sweats. My FBS was between 150-165 and I visited my doctor and some tests confirmed and he diagnosed me with NASH and put me on Atorvastatin 10 mg.

He increased my Metformin to 1 g twice daily and I took it for a week and a half and my FBS was still high. He then changed it back to Metformin 500 mg twice daily and Diamicron 30 mg once daily and my FBS is still high. Any suggestions?

I am currently on Presaratan H, Amlodipine 10 mg, and Qlaria.
