I usually go to bed pretty early but I'm finding if I do that these days, I'm pretty much guaranteed to not fall asleep for hours and then continue to wake up. Lastnight, I took my headphones off at midnight. I'm the type of person who needs a lot of sleep and I just hope this doesn't last too long. I feel pretty keyed up all day long and don't even really feel tired - which I assume, is a side effect of the drugs.
