For some folks wellbutrin/bupropion can be used to treat ADHD. It is schedule IV so access is easy and generics (I think generics kinda suck for me with this med) are very cheap. Does it work as good as stimulants? Nope, but its certainly easier to get and can help some people.
I feel going to a GP to get a very restricted stimulant is a uphill battle. Go to a ADHD specialist psych. Despite having diagnosed ADHD since I was ~6, my GP looked at me like I was crazy when I explored getting back on meds. I went to see a specialist instead.
