Concerta makes me feel exhauster, but makes me feel much better on the next day?

I have been taking Concerta 36mg for a while. I have noticed that every time i take it, I feel quite drowsy and tired, I can just fall asleep at any moment (it can be even worse if I forget to eat); however, on the next day, or after I sleep for about 6 hours, I feel more energetic with somewhat less mental fog and with some focusing power on me, is this sort of thing happening to you guys too?
