Staying awak through class?

Hey all!

This year i have been having a lot of trouble staying awake the whole time in Chem class. Its not that its a boring subject, its just that my teacher isnt the most exiting guy. I got nothing against him or anything, he just cant keep my attention so i start to day dream off and sometimes even fall asleep (even when i sit in the front row).

Is there any suggestions you guys have to help me? Its really going to be a problem as the school year progresses and I dont want it to start to be to much more of a trend.

Thanks-
-Mike
