Translation of enajenar

Thank you for writting back so quickly. I learned English when I was a kid, because we've always been in England during summer vacation, since my grandma used to live there when she was still alive.
Anyway, there are a lot of people on board and I no matter how high the waves may be, I always suffer from nausea or seasickness. I have not been on a small boat before. I will have to vomit.
I am glad you know, I have learned Czech and my English is also not that bad, but we could speak in German. I got your message and I want to apologize again. Next time I will do it more accurate.
