Hi,

I've smoked in average 3-4 cigarettes a day for a year and a half. Yesterday night I've smoked aprox. 10 cigarettes and after I woke up I feel that the air I'm inhaling doesn't oxygenate my body, like there isn't enough air. I've noticed that this symptom developed recently (3 weeks) and only after I smoke more than 5-6 cigarettes in a few hours.

What could it be?

Thank you,
L.
