Feeling guilty about finding the right dosage. This is week two on adderall after a year off of it. We started off at 15mg of XR, but after two days the effects only lasted a couple hours. So we adjusted to 30mg a day ago, and again I feel like after a few hours it wears off. Last time I was on it, I was given IR to keep from "crashing" and things were fine. I mentioned that to this doctor and she doesn't seem to be too keen with the IR idea. I guess I'm just nervous about constantly going up and up on the XR and feeling too wired all day or never finding a dosage that won't help with focus and all that jazz except for a few hours. Then spend the rest of the day feeling tired and unmotivated. Is it normal to feel this way? How long does it take to find that right dosage?
