is this the first adhd med you've tried? a lot of the time people starting on meds have been given unrealistic expectations of what it will feel like. it's not always an extreme difference, especially on lower doses, which is why it's so hard to tell. i would say talk to your doctor about how you're feeling, they might want to try a higher dose, which i think is worthwhile. vyvanse works really well for me, but only at higher doses. and don't forget to consider how it's affecting other areas, like how well you can follow a conversation and get your thoughts together, how much motivation you have for less-pleasant tasks, etc.
