My only brush with unintentional PEDs was because I was feeling congested one morning, I popped a 90mg pseudoephedrine before leaving on my ride. For starting reference, I have absolutely no tolerance for medications-- for me, 1 Benadryl is like a knockout pill, and a Tylenol w/ codeine = 8 hour coma.
So I felt like I had swallowed lightning. I did a 30-mile loop @ 20.4mph and an average HR of 162bpm, just a shade below my LTHR. And I felt grrrrrreaaat. Not even tired... until later that day, when it wore off. I think I went to bed at 8pm.
