Metformin Hydrochloride and different time

I have had severe boughts of diahrrea. I never noticed a problem until my doctor put me on lisonpril along with metformin and flouxetine. I was diagnosed with polycystic ovarian syndrome and was placed on metforming and flouxetine and now the doctor was concerned with my blood pressure fluctuating to the higher side and so he suggested the bp medication. I talked with the doctor about this diahrrea and they suggested I take my meds at a different time during the day and for a week and see if there is a change? If anyone else has had diarrhea like severe, please contact me
