Medication is what works best for me. However, exercise, following a regular schedule, check lists, and being outside all help.

it is the only option for some but setting alarms helped me when i went a month without medication.

Medication changed my life so significantly for the better. I lived with undiagnosed ADHD for nearly 22 years and the change when I started adderall was so rediculous. I can function like a "normal" person. I can screen out sensory input, pay attention to things, remember things, etc etc Obviously do what is right for you, but I seriously recommend trying medicine. Adderall is not tollorance forming and you can realistically expect to be able to stop taking it (under doctor supervision) if it isn't right for you.

No there are several ways of dealing with ADHD besides medication. In a nutshell though intervention is a twofold mission- medication/supplementation/diet and learning coping skills/talk therapy/coaching. So basically taking something and learning something. Self awareness is just important as feeding your brain.
