After the last two visits with my gastroenterologist, he said "I don't know what's wrong. What we do next is go and look around." So, we scheduled a colonoscopy. I've been too uncomfortable too much for too long.
I have no memory of the colonoscopy itself. Midazolam is wonderful stuff. Drugs with a 1-4 hour halflife rock, as I was out when I needed to be and awake when it was over. I came home and napped for a few hours, and I'm ready to go to my role-playing session tonight. Well, I will be, after I shower and dress & stuff. After this morning, the rest of the day became, "Seth gets to pamper himself day". I voted for it myself, as I was the only one around.
But everything was normal, so we can rule out anything that my doctor can point to and say "There, that's the problem right there!" So, I shall continue to eat and be uncomfortable, or not eat and be uncomfortable. At least I still have drugs to help that, to some degree.
