Please do not take naps when you come home from work. Especially if they are after the hours of 8pm. This means one of two things:
1) You will remain soundly asleep until 4am, then wake up and not get back to sleep before you have to go to work in the morning. This will make you very tired.
2) You will sleep for an hour or so, then wake up and be awake until the wee hours of the morning, thus giving you very little sleep before you have to get up and go to work in the morning. This will make you very tired.
As you can see, both of these things end in extreme exhaustion, thus permeating the cycle of naps. If there is no work the next morning you may disregard this message. However, if there is work the next morning, it would be appreciated if you would be considerate of this matter.
