I have decided to give up and go back to Dr, or maybe not, lol. 
The e-cit seems to have a delayed reaction. When I took them the first time I was OK for 6-8 hours and then had bad headache, nausea, spaced out feeling. Tried again over 4 days go up to 5mg then yesterday was OK then about 6 hours after taking had attack of diarrhoea (sorry if TMI). As I am taking them because anxiety causes HA and stomach/ D issues it seems a double-edged sword to me. 
I did a search for contra-indications in English as I wanted to make sure I'd understood the (French) leaflet in the box correctly, and the US FDA sheet says e-cit is not compatible with beta-blockers, specifically mentioning propranolol, which I take.
