Both probably. You're not supposed to have Caffeine with Adderall, but having that much sugar is really bad as well. A single can is more sugar than you're supposed to have in a day.
Doesn't help I keep quitting for like a week, drink it one day, and after that get super fucked up for 2-3 days after. It's really not a good idea to quit something and then when your body is almost used to not having it you reintroduce it.
It's primarily the Caffeine though, I know because I used to drink soda every day for a very long time, and would get insane headaches if I didn't have it. Managed to mostly quit and those headaches went away fully along with a lot of my anxiety and general asshole attitude.
Don't drink Soda, it's so fucking bad for you. Don't even drink diet, just quit. Be ready for insane withdrawl symptoms that you'd think would be impossible to get from drinking soda though.

I made the mistake of drinking a mini-can to try and quell this and now all the awfulness from when I drank soda every day is back. DON'T DRINK SODA
