Vyvanse seems to be working at controlling my ADD symptoms. My MD increased me from 30 to 40 mg once daily because later in the evenings around 7-9 I would notice my symptoms of not being able to focus while reading and feeling unmotivated and a lack of energy. Increasing the dose helped but I'm still experiening lack of energy and motivation tondo things in the evenings. I'm wondering if anyone else has had similar issues and finds that it is better to split a dose throughout the day rather than increase a single dose?
