I take Concerta, and there's actually a bit of dependency associated with it. I notice that I get headaches and feel really crummy if I don't take it every day. Through Tricare, I can actually get a three month prescription, but that's only if it's mailed. Otherwise, I have to get a 1 month supply from the doctor.

I take it every day, not because I feel like there's a benefit to taking it consecutively, but because it makes my life so much more manageable. When I don't take it, I can't focus at ALL unless I'm able to move around and get my blood pumping. But if I'm not moving, I feel sluggish and tired, and I feel less motivated to get up and move, which starts a cycle. Playing video games helps me a lot if I don't have my meds, but I can't do that if I'm at school or going out somewhere. I take it every day so that I can actually think.
