Heya Scott,
Welcome to BL. I’m sure you've had a look around already and seen a few of the great resources available. I myself was diagnosed with ADHD when I was in school, never taken medication for it though, would be interested in how you are finding the Ritalin (do they help, do you think? any side effects? How old are you if you don't mind me asking? How long and what dose are you on? etc)
I’m also in Aus, Gold Coast. Where about in AU are you (I promise I won’t come look through your shower window

)
Couple of things:
I recommend checking out the greenlight guide (in the green box at the top of your page).
Also, the Mods and Staff here are all FANTASTIC. If you ever have any questions or need help, hit any of them up, they are great.
Hit up the social threads (Basic drug info social, and New member social), they are a great way to meet new friends.
PM me if I can ever be of service,
Again, Welcome to the site.
Jeck
