I had one last year. I think the worst part is when you are laying on the table for the scan part and they say "DO NOT FALL ASLEEP!" You are there for 20 minutes not able to move! How can you not fall asleep?! Plus you can't move! I was so glad to have that thing over with and hope I never have to have another one. Luckily my problems ended up being the medication I take for my acid reflux, had stopped working for me and required a new one. Good luck with the results, hope everything is okay.
