Has anyone else seen this?

For the last few weeks or so I have been concerned that Gracies reflux is acting up again. The smallest thing will make her vomit, also she has had alot of hiccups. But something happened last night that I cannot explain. She ate her lunch at about 12:30 or so, she was offered two hotdogs but ate maybe half of it. At 9:30 at night she coughed a little and then started vomiting. I know this is gross but as I was cleaning it up I noticed a lot of full chunks of undigested hotdog in it. I don't understand how 9 hours later there was still food that had not been digested, at all. She had refused dinner, but this is not uncommon. Otherwise she was not abnormal any other way all day. Also for the past few weeks her coordination has been off and she has had a lot of constipation. Any ideas? I'm lost on this one.
