For years I took 40 milligrams of XR Adderall every day. Made a huge difference in being able to focus among all the distractions in an office environment. Once I began working from home I just quit refilling the prescription. There was zero desire to keep taking it, and it never made me feel any sort of rush/high. Evidently there's something to the idea it doesn't impact those of us with ADD like it does normal people. Been about ten years now, and the only time I even think of it is when someone brings it up, yet I have a very addictive personality. Weird. Forgot to mention, my blood pressure went up after I quit taking it.
