I calling my doctor today and making an appointment. So I woke up at 4am this morning.I am not exactly sure why I woke up.I walked downstairs to get a drink of water.I get to the sink and all of a sudden I can't hear everything is really muffled.i can't hardly see everything gets dark and blurry. I all of a sudden feel really sick and nauseas. I pull myself and get grab my water. I all of sudden get vision and hearing back as I am sitting there drinking my water.I am very healthy . I was laying out in the sun and got a really good burn. Could it have been just dehydration?
