A question about add adhd and what some genuine opinons are. Deciding what step to take...?

when i was young i had adhd and took ritalin... now its been 15 yrs or so. I'm in college and have a hard time paying attention. more then that, i have a hard time staying on topic... like my brain just moves by so fast, that nothing really gets processed thuroughly...it's like i forget to come back to a thought, and the day just goes on. I have to managed things externally with all kinds of notes and a strict schedual. But then i can focus sometimes and analyse things that most people cant. NOw, the question is... should i look into some meds now? can anyone relate to this...? sometimes it is just almost impossible to focus on something.... i'll get done reading and think "what did i just read?"... i'll forget classes i've taken, almost immediately. it's like life just keeps going by without things that i learn really integrating.... ok ....so meds? any stories or ideas? thanks for your time.
