Thanks for all the well wishes, gang. I personally am leaning toward the theory that I have a vagus nerve problem, possibly triggered by acid reflux. If you don't know what the vagus nerve is and are just dying to know, I suggest you Google it. It's amazing how many functions in your body are connected to that nerve and what it can do to you if it's out of sorts.
I have an appointment with a cardiologist next week to hopefully rule out any problems with my heart itself. In the mean time, I'm just trying to hang in there and make some progress on these various projects when I can. I will definitely have some more progress to show before the end of this weekend.
