No, don't feel bad LP jaan. IMHO 2-4 a.m. is the absolute worst time to watch a game because you can't get your REM sleep either before or after the match.
For earlier matches you can just stay up and go to sleep after and for later matches you can sleep and get up early, but this time slot is just the worst. I struggled BIG time for the Guam-Iran match and was a total write-off the next day.
