I was diagnosed in 5th grade - which was in 1989...damn I'm old. Anyways, they couldn't figure out what was 'wrong' with me. Why I couldn't focus on what THEY wanted me to focus on, often finding my own "thing" to do - pretty much all of the time.

Thankfully, my parents were both teachers and basically refused the idea that I should be put into remedial classes. They cycled me through a bunch of psychiatrists and counselors, which allowed them to demonstrate I had an IQ of 142 and was actually quite bright. Eventually the recommendation was to take me to a neurologist, and a cat scan revealed I have a "more pronounced" film between the two lobes of my brain that likely impedes proper communication between the two. The RX I was on back in 89 was rittalin (whatever the other suggestion was required monthly blood tests, and I've always had a healthy fear of hypodermic needles).

As an adult, the inability to 'focus' on one thing has gone away, and been replaced by "hyperfocus" the problem with hyperfocus is that I have little control over what I direct it at without help.

For years I self medicated with MJ, and it made me feel 'better' but it didn't really fix my issue.

A low dose of Adderall XR (15mg) a day is the ticket for me. So very much so that my wife/colleagues/friends/etc can notice when I "forget my meds in the morning" truly ADD is a "thing" and it sucks if you have it. Mostly it sucks because our laws on controlled substances are so very overbearing that just "dealing" with having an adderall Rx is a supreme chore. Every month I have to go and on the very day I run out, get a physically written Rx (I can't have more than a 30 day supply at a time, and I need to renew on the DAY I run out - I can't fill it the day I have 1 pill left proactively). It is an immense hassle. Also of note, is that with proper medication MJ isn't even a side thought.
