Hi all, I'm currently on 90 mg of Concerta and have been on it for months. Unfortunately, I realized Friday night that I ran out of pills and my doctor can't fill my script until Tuesday (office is close monday, don't ask me why!) I have left over 18 mg of Concerta and was wondering if anyone has 'doubled up' on pills in order to meet their dose. My Dr. has told me before I could always double if I ran out, but it just makes me nervous because that's a lot of pills at once!

Normally, I would just wait the few days but I'm in law school and get almost all of my work done on the weekends and I'm really struggling without it! If anyone could give advice it would be greatly appreciated
