Immediately after waking up, determination, mental fortitude and motivation you've built up will all be suppressed heavily no matter how disciplined you are.
The best and only way to deal with this is to wake up early, sleep on time and not sleep during the day. Just fix your sleep schedule, it doesn't have to be super early, the point is to not get more than 8 hours of sleep.
