This mirrors my personal experience. I never really needed to study in HS so never did. In college, I never studied for a test other than the night/weekend before until my 4th year because I didn't know how/couldn't focus and for the most part did alright until 3rd year. Grad school was easy, started group studying and did well with others keeping me redirected. My med school curriculum was a little different with it being a 2-pass systems based approach, so M1 year was easy as it was basically just a review of cell bio, physiology, anatomy, etc, aka all the classes I'd already taken. M2 year was crushing trying to learn all new information for every organ system. I spent 12-16 hours a day "studying" with probably 4-6 of those hours being actual quality studying and the rest being distractions/trying to remind myself what I was even trying to learn. I had been on one or 2 SSRIs for "depression" and "anxiety" (which I'm sure there was some of), but didn't help with performance at all. I started Wellbutrin in residency and within a week my functioning/performance changed dramatically. My notes were far more concise/direct, I was finishing work for the day at 2-3pm at the latest instead of 7-8pm regularly, I could also just tell I was less impulsive with conversations and some of the attendings actually felt like I was a completely different resident and said so in evals. I've never taken a stimulant and don't have a strong desire to, but I have always been curious about what it would be like as someone who has benefitted from Wellbutrin the way I have.
This also mirrors my experience. Wellbutrin is helpful but I hate taking it and most people with ADHD I've talked to and treated prefer not to take meds but suffer without them. I've found that the people who come in demanding stimulants are usually the people who don't actually need them unless they've got something acute going on effecting their emotional regulation (aka, I'm about to get fired because I can't get my work done).
