I feel for ya, Dej.

I cannot imagine feeling like you do. I hope it's over with quickly for you. Seems like it's more than just not liking the procedure or the equipment.....it's painful for you and physically draining.
Can I ask why you're having the MRI? Is it because of the MS? I haven't had an MRI in four years. And the only reason I kept having them at my Neuro's request was because insurance covered it 100%. If it hadn't I wouldn't have had them.
