Why would your doctor recommend you not take Adderall on the weekends? I take Adderall XR almost every single day because I need to focus on the weekends, too. I know taking breaks used to be the recommendation, but unless you have a side effect that requires it, I would insist on taking it daily. On the occasion that I don’t take it, I do tend to have a bit of a crash. It’s usually because we’ve planned on a lazy day, though, so it’s not a huge issue.
Also, my daughter takes Adderall non-XR because XR didn’t work for her. She’s a high school senior/college freshman (early enrollment), and we’ve had no crash issues because if she needs it, she takes it. There’s no reason to not use medication when you need it.
