I'm unmedicated but I've been diagnosed since I was 6/7 so it's not like I don't have it. ADHD affects me more in the inattentive (I'm forgetful and easily distracted )type now so medication wouldn't be as effective for me like when I was a preteen who was more impulsive. I manage my forgetfulness with a fuck load of notes and calender reminders and to do lists. Anyway coffee used to make me tired when I was medicated. So reaction to coffee isn't indicative of anything.
