I just went back to a psych to begin a new regime to control my ADHD symptoms for college. He started me on 10mg XR once daily, but since I had been taking 20mg IRs for the past year or so to get by with school work it was nothing. He switched me to 10mg IR twice daily. Someone mentioned in an earlier post that 10mg should last all day, which is false, unless you have a very very low tolerance. A regular dose of IR adderall will last for about 4hrs, which is why docs have you redoes at lunch time. My script will be getting bumped up higher because my current dose is much too low since I've been prescribed add since high school and have been taking it on and off for several years.
I tend to take 40mg IR at once when wanting to buzz a little and then re-dosing a few hours later. A lot of if has to do with your natural inherent tolerance, built up tolerance and body weight/composition/sex.
