Hospital

Okay, so the vomiting didn't stop.
He only got a tiny break from it.

And he suddenly became excessively tired.  So they chose to hospitalize him and do a bunch of new tests, and also some that they've been wanting to repeat, like his MRI.  His last MRI was three years ago.  So they did a scan of his abdomen, more blood and urine work, and monitored everything going in and everything coming out.
I noticed all week I was having to expand his waist on his pants, so when I had to let it all the way out within 4 days, I was alarmed.  I could see the bloating. :( I felt so bad for him, he was truly miserable.

After I insisted something be done to help him out, they took care of it.

What little info I have from his test results is that they can't find anything that would cause all this vomiting.
As he seemed to improve, looked better, started talking again, eating and drinking a little more, I was relaxing.  They discharged him tonight and we came home.
We were barely home and he vomited everything he ate and drank today.  And then after getting him to drink some more water, he threw that up too.
We are letting him sleep in his bed tonight, because he had the IV until just a few hours ago.  In the morning he'll have to go back to the ER for another IV.
I'm convinced even more than ever, it's the seizures doing this.
I've lost count how many seizures he's having a day.  Every time his medications have been working well, this vomiting has reduced significantly.
But whether or not I'm right, he still has to have another IV.  He's already got two very sore arms.
My Little Man is miserable and it breaks my heart.
