ask them for some xanax or talk to your doctor ahead of time. They have no problem with it; many people can't stand to be enclosed (me included) and a small dose works very well. You will need to bring someone with; they don't want you driving..........if you take it
welcome to our group
The jerks are possibly associated with your medical condition - although you haven't said you have MS. You could also ask for valium - any thing that relaxes you while you have the MRI might slow down the jerks.
Good luck and come back and tell us more about yourself and your tests when they are done.
