Do you drink anything with caffeine in the hours before going to bed? :)

I drink coffee before bed haha!

No I still drink caffeine before bed. I don't know if it affects my sleep. Maybe. I fall asleep really hard too, so it could be that. However, I don't always drink caffeine right before bed, but usually.

I voted 'Other', because the fact of the matter is that caffeine before bed time will make it more difficult to sleep, but my internal clock is so screwy that I often don't sleep on a normal schedule, and will often end up drinking it before I do go to bed. The average half life of caffeine is five hours, and for me specifically, it's about 2.5 hours (but yours may be very different), but I may drink several cups a day, and thus have the compound effects of those drinks.
If you think it's affecting your sleep, no matter how small the amount, I'd suggest figuring out if there's some way you could either ween yourself off of it short term, or stop drinking it after say...5 PM, for about a month, to see how your body reacts, and whether or not it helps your sleep.
