Need tips

[Curb]

So today I went for my MRI on my back, well lets just say things didn't go according to my plan. This was my first ever MRI and I didn't know what to expect. He put me in the first time and when it got up to my face I started freaking out a bit. He took me out and gave me a blindfold and we got started...1st sequence no prob...2nd, I tried to take a deep breathe and my chest hit the top of the machine and I started to flip out again and had to stop. The tech said I could try some xanax or valium to try and mellow me out...is there anyone out there who's had one and had the same reaction that I did that can give me advice.

oh and yes it was an open MRI

TIA


and please no comments from the peanut gallery, i'm getting enough from my sister
