After midnight....

Yeah, you probably would have guessed----werewolf?? Sadly that's not the case.
These days it's so difficult for me to sleep. Part of the reason is because of the sudden death of my grandma, and having to have a miserable Chinese New Year.
It's always after midnight that i would look @ my clock, checking the time...yeah it's half pass midnight now....yeah it's 3:00am in the morning, and yay! it's 6:30am in the morning! Time to go to work! And i would spend the rest of my day miserably. When will i be able to go back to my old routine?
Could anyone that has got good tips of curing insomnia drop me a line please??
