zzz...help me get out of this.....

it had been 3 weeks,
since i start my 2nd semester,
this happened in almost every study days
i had adequate night time sleep
but i would just be in extreme drowsiness whenever i am having lectures
( i am just normal and alert for the rest of the day)
its totally uncontrollable,
i would just fall asleep in inappropriate times,
i really hate it
i missed those important infomations in those lectures
but i just cant find any better way to get rid of this problem at this moment...
the one and only day that i remained extra energetic and refreshing throughout the lectures is the day that i sipped a cup of coffee for breakfast...
but i am not going to do this daily
having coffee for breakfast is not good for health
hopefully i can find out a good solution for this problem very very soon...
