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. i am 34 male hypertensive and currently taking atenolol, amlodipine, moduretic and captopril to control my hypertension, don't knwo if it is a drug interraction, i am not sure cos at times i will smoke it doesn't occur. anyway have decided to quit, this is my second day off cigs, but if i can know the cause and treatment i might go on enjoying my cigs
