my cardio of choice is stationary bike, and I try to do 1 hour sessions, but I don't know when to do it

I'm not a morning person, and it would be very hard to wake up at 6am to do my routine on empty stomach (which is the best, acc to various sources).
I would like to exercise about 8pm, but the last couple of times I did it, I felt great for about 20mins after exercise, but then I started to feel like I'm going to throw up and I had to go to sleep because I couldn't do nothing but lie down on the couch
I was careful to exercise 3 hours after I ate, and I didn't eat anything afterwards.
is there anyone with the same problem? any advice would be appreciated
