I'm so glad that you are O.K. and the tests are done! The first couple of endoscopies I had done, I was out like a light and didn't remember a thing, but similar to Hello-Kitty, my last 3 endoscopy's I was 100% awake for and it was horrible. I tried to tell them as they went to put the thing in my mouth that I was wide awake, but with that kind of sedation, I guess it's common for people to still be able to talk, but they don't remember any of it later, so they didn't believe me and just held me down and shoved a bite guard in my mouth that made it impossible for me to talk. I kept moaning and groaning, but at the same time I was gagging from the hose they were shoving down my throat.
Each time they told me they needed to do another one, I told them of my previous experience and they assured me that they would not do the test without me being out, and each time it was the same thing again. I strongly believe that my years of being on pain meds has caused me to have a very high tolerance to the meds they use to sedate you.
I, too, was very concerned about what your experience was going to be like, but I did not want to scare you unneccessarily, so I am so glad that everything went well. Get some rest and indulge in that bag of M & M's just one more time, you deserve it!
