I felt lousy yesterday but rode anyway. I was not sure if it's bad allergy or somthing else. Well, it was a terrible 30 miles ride back from work as breathing was really difficult. It felt like I was sucking air through a straw. Got, took a shower and bascially crashed in bed. Woke up and still feel lousy this morning even though breathing is a bit better, I took the bus to work. The lung feels like it's full of phlegm. Now that I think about it, that sounds like hay fever.
