I went for a walk on cliffs last night (on holiday in Cornwall) and after about 10 minutes suddenly found myself sitting on the grass crying and feeling very disorientated. No one was about so started walking back but felt very achey and everything spinning. There were steps and I had to get am elderly couple to help me down as I felt so dizzy and couldnt balance properly.they were very kind but I think they assumed I was drunk 
In the past I've only had seizures in my sleep so what the hell happened. Still feeling shakey now
