Thank you for your query.
I can understand your dilemma. I suggest that you consult your doctor who has advised you Adderal and discuss if the dose can be reduced. As you mention your vision has deteriorated and you have constant headaches
, it is all the more reason to get an evaluation done.
, it can be diagonsed by a simple blood test
which your doctor can arrange to be performed.
I hope I have responded to your query.
Wishing you all the best.
