I think so. I've been having off balance periods not necessary dizzy. Until last night. I was reading in bed and fell asleep. I awoke to a violent spinning of the room. Didn't last long. I sat up and it slowed down. I got really hot and nauseous Finally went back to sleep. No problems today. Just lazy feeling. But it scared me. Live by myself. 65 and diabetic. YYYY@YYYY
