I did my own personal research in the 90s as an asthmatic and every time I would drink coffee I'd have an asthma attack shortly after. I stopped drinking coffee then and didn't know the specifics, I just knew it was not to be consumed in that manner if its consumable at all - lest we find out in the coming years.
What were your coffee drinking habits, @shaan2080? Which coffee? How much? What time of the day? Do you feel better since you have stopped drinking it?
