It varies for me.
If I don't put back sleep till too late at night then I fine. Most of the time I'll get out of bed waiting to start a new day but then I'll have the odd day were I'll wake up, 'close my eyes' for five minutes, wake up again, another 'few' minutes in bed and then when I wake up again I feel rotten and annoyed because I haven't woken up earlier, resulting in a few more minutes in bed awake, being too lazy to get up.
