8 months seems quick. I was like you Mounty, 190/110 when caught. Family genetics and stress at the heart of it. Currently on Candesartan and Lacidipine. BP ranges from 110/70 to 135/85, so very happy with that. Had a bunch of heart and blood tests to see if I'd messed myself up with the long term BP and stress. Lots of ECGs, exercise stress test, 24hr monitor, Ultrasound etc. Thankfully no lasting damage, and getting a good amount of help with the stress and how to deal with things better without becoming overwhelmed.
I'd say it's worth having a BP monitor at home, and checking it often in the first week or so after a change in meds, but not letting it become a worry in itself if you can manage that. What that did for me was allowing me to recognise what peaks and troughs in BP felt like, biofeedback, like tj says, so when I feel stress and BP, I can take a little time out and go for a walk/calming music/breathing exercises/mindfulness etc and get back on track. Talk to the doctors a lot and tell them everything, as you can tell from this thread there are a lot of options for meds and most people can find one that both works and they can deal with.
