I have been on a low dose propranolol but it didn't work so my gp put me on a low dose water tablet which made me feel really yucky so I stopped, I have been taking hawthorn tablets from health shop, magnesium 500mg and potassium 200 mg daily and as far as I know since it is much better I should be able to convince them this week that I can now come off the propranolol.
All those tablets have side-effects, I don't think the natural herb and supplements do so am happy to take these for ever! You can also take garlic supplements if you can afford to keep buying everything under the sun, which I can't.
The other thing is to of course take regular exercise (which I'm not doing!) and cut down on caffeine.
I just hate taking those tablets they prescribe, I guarantee you you will feel worse once they kick in, even if they regulate your bp.
100/150 reading isn't so bad, others have it a lot worse. Mine was that at its highest point but only cos I was stressed and eating crap and constantly on the go. I am sure the supplements and hawthorn really help and is well worth trying first. You should be able to tell after 8 weeks and their tablets from the gp won't work any quicker either!
Sorry, hope I didn't offend anybody medical!
