If my experience is relevant at all, don’t know. I had a really hard time getting work done and staying focused at the office to the point where I almost lost my job. I suspected it was because I was not getting enough sleep. Dr said not to drink coffee or take stimulant meds in the afternoon or evening. My health overall and mood and ability to function were getting worse, so I knew something big had to change. I stopped taking meds altogether, almost stopping cold-turkey, and almost all my problems are solved. It wasn’t insomnia or ADD, it was the prescriptions I was taking that were supposed to be helping me. The original symptoms I had seem like nothing compared to the destructive side effects.
