Started off with a good start to the day, preparing hot food to take down to our local Church Faith Lunch. Got down to the hall, on my feet quite a lot doing this that and the other as one does! Gradually could feel myself going very light headed, weak, life just seemed to be draining away. Sat down good friends were asking, but don't like to create a fuss, eventually drove Back home - not too far - checked BP 158/91 HR57 ( which is exceptional for me usually 42)! Beem home around 3hrs feel so drained out - plus still light headed and breathless. Thank goodness on Pradaxa no TIA, which happened in the past, and Amiodarone keeps the HR at a steady 42. So just sat relaxed - methinks and take it steady. Should have been driving 65/70miles later on today to daughters so that's called off.
