Feeling giddy. Blacked out. Anyone else?

[astrocan]

Had electrodes stuck to my head. Been through a MRI scanner which was like seeing to a really rubbish Hawkwind tribute act. Had an armful removed and tested. Just about to go and have a cardio monitor fitted for 24hrs then back to see if they can tell me why.
I am hoping for nothing significant and will also try to answer the question in my OP regarding cold conditions lowering an individuals seizure threshold.

Reading Lulubel s experience seems to indicate that it might and the symptoms described there do corelate closely to mine which is encouraging.

Thanks for your kind comments and concern. It helps a lot.
