for about a week now i've noticed that i experience an acute loss or respiratory drive when i smoke, maybe just after a few drags or a few mins after i finsh smoking, first time it was very serious i had to get out of the car and force my self to breathe, later on i realised that the symptom is relieved by alcohol. and if i smoke and drink it doesn't happen, also it doesn't happen every time i smoke, just starts out of the blue. will like to know the cause and treatment.
