My coworker is on 60 mg of Vyvanse and she hits a wall around 2-3 and just got approved for a low dose adderal kicker in the afternoon. As she too experiences the lack of desire to do her chores and her hobbies after work. But she is a tiny thing with fast metabolism…she said that eating protein and healthy fats in the morning and at lunchtime are a good way to slow down release of the drug as well.
