I too have had a TIA, but not a very long one. I was driving at the time, going down a dual carriage way to buy some petrol. Then I was coming to driving down a rural road I did not recognise. After a distance I saw a sign that said I was on a very long(1 mile plus) slip road for the local motorway.
To get there I must have come off the dual carriagway where I planned to come off, but instead of going three quarters round the roundabout , I went right round back to the dual carriageway I had just come off, but going in the opposite direction. I had driven some miles down it, done the three quarter turn at another roundabout and headed off. down roads I did know but not well.
I considered going to the doctor, but my usual rule is not to visit the doctor until the second time something happens, The event was relatively short lived and, as Bluebelle says, it only happens once.
Like her friend one of my friends had a similar episode. he was chairing a day school I and other friends were attending. He seemed his usual cheerful self, if slightly subdued, he chaired the Day school as well as ever. His TIA lasted about 12 hours.
