I used to be prescribed lisdexamfetamine for ADHD and after 3 years it did feel "a bridge too far for me" as well.

My stimulant of choice now is low-dose nicotine patches which I feel is extremely underrated, and demonised because of the effects of smoking and vaping. Mind you: I am an ex-smoker and I am quite aware of how strong the addiction can be, yet pure nicotine is the most mellow stimulant there is.

It's been 2 years now since I replaced my ADHD medication with nicotine and I haven't felt the need to increase the dosage. It's cheaper, lasts MUCH longer, doesn't cause anxiety and it doesn't push you around like amphetamine.

YMMV.
