Have you considered high EPA fish oil which has been helpful for some people with ADHD?
I am trying out this brand:

It seems to be helpful although I haven't been on it long enough to say yay or nay.
But when I was at work, I remembered to check a document in an email I might have neglected to check previously. I found that encouraging.
It can be purchased at your local CVS drug store which is convenient. It isn't cheap though which is a downside.
If you wanted to try a cheaper high EPA fish oil, you could look at Country Life Omega Mood:

It didn't do much for me but it has worked for other people.
By the way, I have no connections whatsoever to any of these products.
Also, I am not on any stimulant meds as an FYI.
Good luck as I know dealing with med side effect is very frustrating.
