Just to say I took another one on Sunday (after my trip to London on Saturday) as I woke up with acute anxiety (I think I'd pushed my nervous system a bit too much). The beta blocker calmed everything down which helped.
I spoke to my Dr today and i am going to take 40mg beta blockers daily - 1 on waking and, if I need to, another 6 hours later. She said that it should help deal with the anxiety in the morning and even out any surges of adrenalin (which I tend to get first thing in the morning).
So feeling more optimistic about things now. She also said that 40mg is a really small dose. Apparently it comes in as high a dose as 110mg! But she said that she's found that less than 40mg doesn't work for a lot of people - even though it comes in 10mg as well. She said if I find that two 40mg doses a day are too much, she can prescribe the 10mg as well and then I would take 1 40mg and 1 10mg a day. But for the moment I'm going to see how 1 40mg dose a day works.
This morning I didn't have much anxiety which helped as well - I think it only happens when I push myself a bit too much more than my nervous system is fully ready for. But I also did extra yoga and meditation yesterday which really helped.
