slip?

I've had my band almost 18 months.  On Wed night I started vomiting, Thurs AM went to ER, my band had tightened so nothing was going through it.  My band was emptied.  Starting Friday, anything I eat or drink causes nausea.  I have read that these are symptoms of a slip.  Having upper GI on Tuesday.  Any input would be much appreciated.

I think it's a good sign that things are staying down, even if you feel nauseous. My doc. told me with a slip suddenly you can't keep anything down, even water. I hope you don't have a slip and feel better soon.

Things are staying down now, wed nite/thurs am they were not.  Once my band was empty I was fine.
