I was woken up in the night last week with the most horrendous sensation of the room spinning really fast - it was terrifying. I then found i felt ok if my head was straight but if I tilt head or roll over in bed I am really dizzy. I have to sleep on my back. I went to doctor and and he said I had vertigo....prescribed Prochlorperazine tablets but I daren't take them after reading long list of side effects. Does anyone have any experience of using anti histimines instead? Or anything else that helped. How long were you signed off work for? I'm back at docs next week. :-(
