I'm a smoker, when I wake up in the morning I go smoke a cigarette. 3 times in the last 2 months I've done my morning ritual and gone to use the bathroom, in the short 20 feet to the bathroom I get dizzy, my vision goes in and out, I can still breath but only quick short breaths, I sweat profusely and I feel sick to my stomach. It only lasts about 5 minutes, but today was the worst episode I've had. I was walking to the bathroom and next thing I knew I was laying on the hallway floor in front of the bathroom.
