Im 30. occasionally when i say alot and am almost about to take another breath, like i've completely exhaled, i feel this flutter almost like need to cough to stay alive. like a tickle in my chest. no prior medical problems, no smoking. normal?

Flutter: This may indicate a transient cardiac dysrhythmia-possible premature atrial or ventricular beat. I suggest wearing an outpatient heart monitor which would record your heart activity for 24-48 continuous hours. You would make note of the time you experience any symptoms. If no flutters occur during that test, arrangements can be made for a longer monitoring period. Discuss this with your physician.

Anxiety? Cough: variant asthma? Post nasal drip? It is difficult to say what it is without a physical exam and some tests. When this started ? When was your last medical check up?
