I am a 5'7 tall, 214 pound, 39 yr old women, my BP is normal, recently I've been getting dizzy when I look up, when I bend down to tie my shoes, and when I put my head on the pillow to go to sleep and when I get up in the morning. Its really bad when I am in bed because I feel thowing up, and even thow I close my eye I still feel the dizzyness
