I've suffered from anxiety and PA's for over 20 years. I also drank for many years to self medicate. However, the alcohol worked in reverse and made my anxiety and PA's 10 times worse!! My heart would race in the middle of the night after a bottle or two of wine. Now that I'm sober, I feel 100 percent better. Sure the anixety is still there, but it's not out of freaking control like it was when I was drinking. Incidentally, I spent time in detox (2 times) and anxiety and PA's triggered by alcohol is common. Oh and so is raging blood pressure and an elevated heart rate. I've seen people with BP's at 200/110 with HR at around 110bpm. Some hallucinate and have seizures. It's not a pleasant sight at all.
My advice to you is to completely lay off the booze. Booze even in small amounts will elevate your BP, especially if your hypertension sensitive. Maybe as you wean off the BP meds, (I say maybe) you will be able to have an occasional drink now and then. But for now, I would abstain if I were you.
