I am having diziness at night, the moment I put my head on the pillow, I felt like I am falling, this happens a couple of months back. Just three days ago, this problem came back, this happens when I woke up from bed and I felt the spinning diziness. Every time I try to lie down I had this feeling. These two nights I had phobia sleeping. In fact last night I slept well but when I woke up to go toilet, I had this spinning effect again, and after that I have to sit up and sleep. I was told to take Metoclopramide - 3 times a day, and some one recommended that I take betaserc twice a day.May I ask what is my problem. I went for after waking up,
