I’d like to just throw this out there for anyone who is on Adderall. If you mix it with alcohol, you will get fucked up. It’s called “dirty rolling” and it essentially mimics the effects of MDMA. I’m not sure if the effects are the same for Ritalin or Concerta since those are methylphenidates and not an amphetamine, like Adderall, but just a warning.
What it will feel like is intense euphoria, your motor skills will be at the level of “plastered, falling on your ass” drunk, your pupils will get huge, your sex drive will go through the roof–past what usually happens if you take ADHD/ADD medication long-term-- and you won’t be able to sleep.
Basically, just don’t do it. It will mess with your life. If you are on Adderall or something similar and you want to drink, don’t take your medication at least a day beforehand.
