I think I've been using caffeine to s self-medicate for it. When I was on Adderall I stopped craving caffeine. On my new med it's a lot easier to just forget my morning soda that I "needed"
Not surprising when you consider that the impaired executive function associated with ADHD (and mitigated by medication) is known to frequently manifest in the form of weakened self-inhibition.
Anecdotally speaking, whenever I personally go without medication, I am endlessly distracted by even the most basic urges (i.e.: hunger, exhaustion, arousal). Even being slightly peckish would leave me growing increasingly irritated and uncooperative. I've never smoked, but you wouldn't know that by looking at my unmedicated habits -- taking breaks every 20 minutes to satisfy some random urge before I inevitably start losing my head.
