I was diagnosed with "Essential Hypertension" around 15 years ago. My GP tried several drugs before we settling on Atenolol which keeps it under control without any undue side effects. I did try various drugs at first (I can't remember their names now), the worst of which gave me a really bad, almost uncontrollable dry cough and others which made me feel very tired.
TBH I'm not sure whether taking Atenolol very long term is a good thing but it seems to do the job. I think you'll need to try and see what works for you - which might take a bit of "suck it and see".
