Thanks for everyone's opinion. Last night I put in the original 512MB that came with my MacBook and I only lost around 2% of my battery. So the extra RAM must be the cause of the abnormal drain.

Now that I know nothing is wrong with my MacBook, I can rest easy. While I do lose a fair amount of battery power in sleep, I'll just have to keep that in mind when putting my MacBook to sleep for extended periods of time. Thanks again.
