Just bring it up to your T... explain you are worried about the asthma attacks and you may have to stop and use an inhaler once in awhile. You maybe embarrassed, but I am sure T would totally understand. I felt a bit embarrased yesterday, when I left my T and found that my chest and neck were all splotchy from nervousness that came from the topic were talking about. But, I just had to tell myself that I am sure he has seen it before, and it it compelty normal response to nervous feelings.
