is a small dose of prescribed adhd med enough to make me a crappy actor?

2.5 mg adderall/day..This is a med I am prescribed but I haven't gotten any parts this year and I'm wondering if the aderall is making me into a zombie or uninteresting? I feel like it helps give me motivation to get things done and not be mired down by depression. I don't take it on all on audition days but I still haven't gotten any roles...its such a low dose but I know I probably shouldn't take it to be a good actor? I'm also 37Female so maybe I'm getting too old to be ineresting on camera? Does anyone have advice on this? Thank you
