Woke up in the night and felt incredibly dizzy, room was spinning, my head was spinning, I felt nauseous. Tried to get back to sleep but ended up vomiting. I almost fell over trying to get to the bathroom and I couldn't see straight. After that I still felt as dizzy but I did manage to sleep. This morning I still feel a bit dizzy and lightheaded. Does it sound like vertigo? I've never had it before.
