Can you tell when your tablet is wearing off

I am a little confused. Every day at the same time I feel like the effect of the tablets are wearing off or is it the effects of the tablets?
Generally starts at about 2pm (I take my tablet at 5am) I get the shakes, headaches, my head feels like its building up with pressure and I feel somewhat out of control. I am really snappy. I also feel like I have been hit by a bus. Kinda like I am coming down with something. I am on 30mg. I don't have any effects of the tablets before this time...
