For those who take adderall daily...

[miami32]

I started taking adderall last month. I've taken it twice a day since june 20th. Today is the first day I've gone with out since my persciption ran out and I literally feel awful. My stomach is off and my head is hazy. Is this standard? I mean it's not a big deal, I get more tomorrow, but I can imagine what it will feel like quiting after a year or so. Does anyone have any experience with this?
