Hi Nic, its not a failure at all, you were feeling pretty rotten even before you got to the hospital, so perhaps on a day you had felt more generally well you might have managed it, dont be so hard on yourself.
the consultant who sent me for one, told me he wouldnt like to go in it either!!
If you wanted to try again, i would recomend some sort of sedation, i took small doses of valium from the night before my appointment ( i never take a tablet, even for headache unless i need to) up until my appointment, because i was so so scared, and it really did help. and as you now know how tight it is, i had to make sure i kept my eyes closed or i wouldnt have been able to stay in it.

Anyway, hope you get back to 'normal' soon.
