Hi, i'm 36, been drinking various amounts of alcohol for about 20 years now. Not in any excessive way, just the normal pint with my friends or bottle of wine over dinner with my wife. In the last two weeks though when i've had slightly more than say a glass of wine or a pint of beeer i've lost vision in my left eye. It's really freaking me out and obviously i'll try and see the doctor but does anyone know about anything like this?
