Yeah, when I said sleepiness, I meant "oh my gosh, can't keep my eyes open, and I'm going to fall asleep right here and now." Once I gave in to that, it only lasted about half an hour. So, I take it SUPER early in the morning - like 4 am, and then go back to bed and sleep through the sleepiness. When I wake up again at 6:30, I'm fine. But, I tend to have weird reactions to meds, so....
