It increases your urine output. Yes, it can mess with your blood sugar

you get exercise every day (plus avoid processed foods, sweets, fast food, etc.) you should be okay.
ACE inhibitors are another class of meds for high blood pressure. I'd ask your prescribing physician for a discussion of all the HPB meds, beta blockers, calcium channel blockers, etc. and the pros and cons for each of them.
