4 hours of sleep again

Don't think I'll be able to get back to sleep tonight. Not sure what's going on. I can try taking Trazodone the next night I guess. I tend to avoid it because it gives me super intense, vivid bizarre dreams. The other problem is I have class on Monday and I don't want to go to bed tomorrow night and end up sleeping 15 hours and missing it, it's the last week of classes before I take my final exam.
