Recovering from jetlag

Imagine typing this at 342 am on Sunday morning. Well, the fact is that I slept since 4 pm the previous Sat afternoon till 342 am. So, the jetlag from the flight is still into me.
I do pray that I be alright by Sunday evening, if not, how am I able to go to work on Monday morning.
Think I better go catch some sleep, at least try to sleep again.
