Unfortunately because I've started several things I can't tell which, but something has made a significant difference in the last 24 hours (apart from lovely responses from MN of cousre :-)
1 - Doctor gave me betablockers - I know in the UK Methyldopa is most common, but apparently BBs are faster to act and shorter half life/don't make you feel so rubbish.
2 - chinese medicine - mistletoe, peony, zizyphus. Disgusting but maybe worth it?
3 - Magnesium supplements.
I'm sure my water retention is less, and my bp has dropped a definite 10+ points each side - so from 140/150 over 90/100 to 135/80.
Just thought I'd write ti down in case someone can use the info.
