Medication and Schedule Reminders

"Our 19-year-old son recently moved back into our home after leaving and struggling to survive in NYC. He was diagnosed with AD/HD when he was 8 years old. He took medication until he was about 14, and stopped because it was difficult for him to make doctor's appointments because he played sports, and also difficult for him to take medication in High School. Now, he is going to an Adult High School program at the community college and working part-time. My question is should we follow up with medication now? He is very unorganized and doesn't follow through." - DLD
