Lifestyle advice & prognosis following dissecting internal carotid aneurism(aneurysm)

I have suffered an internal carotid anuresim following two long transatlantic flights. I presented with a left horners syndrome and was admitted to the UK only neurological centre & treated. I have very limited information about what I'm supposed to do in terms if lifestyle and my prognosis. I'm a clinician taken very early retirement due to SLE.
Only advise I have been given is take it easy, no lifting, straining or driving for four weeks. Help!

I do not smoke and do not find this add posted as a response to my question helpful ! NHS money could be better spent researching the disease I have than wasting money  on some of these useless campaigns.
I worked for 35 years in the NHS and seen public money hemorrhaging to these waste of time adverts !
