I agree about having to knock me out for I do another MRI. I have been subjected to several. They like to track the advancing damage in my spine. The last MRI I went through was hell. I felt like I was being shocked, plus I felt very, very, very off afterwards. It is hard to explain how I felt, but I googled my experience since before MRIs were never a problem. Turns out I am not the only one to experience such things during and after a MRI. It took a day to feel normal again; so, I absolutely do not want to go through one again. Before all of that I had no problem. I even fell asleep during my first MRI. The noises remind me of bad nine inch nail remixes, and I did not have a issue with the confines of it. Nowadays I do have problems with all of that stuff.
