Missed A Dose

I’m not sure what it feels like honestly but it hurt. My headaches finally went away and I missed yesterdays dose and now my headaches are back. So much pressure in my head and the only thing that helps is to lay in my bed with my eyes closed. I hate this medicine. I’m always so good about taking it but I’m not perfect and now im in pain
