Does Hydrochlorothiazide Or Metoprolol Cause Low BP?

Hi my name is Dean, I am a 54 yr old Male with type II diabetes, double CABG at 47, about 3 months ago my BP started running 105-99 over 58-52. I have stopped Hydrochlorothiazide, cut Metopralol in half 50 mg no other BP meds, should there be something I should consider or ask my Dr about
