@racing212, I hope and pray that this is a minor episode for you. Hugs to your foreman for his quick action to get you in for treatment.
I don't know whether you live near your transplant center for treatment, but if not, I hope that they are involved and will be able to figure out what is causing these episodes.
I have not had any HE episodes so I can only try to imagine what you are going thru.
Hugs.
