Translation of umbuchen

At around seven, it wasn't dark anymore, the mother of the family offered me some tea. I felt so uncomfortable coming to a new family owned casa and vomiting there all night, but I was really sick.
How could I get better in Spanish if I had to eat by myself. Impossible. The next days we always ate together and sat around the table for hours discussing politics and the lives we were living.
We went to eat dinner with the Dutch couple in a Sea food restaurant highly recommended in our Lonely Planet Travel Guide Book. It was OK, but we had a great time with our friends.
