I am looking for detailed blogs and advice from people who have ADHD and developed solutions. (websites, books, blog posts etc)
I'm taking a break from medication due to side effects.
Not really a blog, but the most comprehensive website I know with essay-length info on all things ADHD is this one: https://www.adxs.org/en
Otherwise r/ADHD and r/ADHDers are great resources on reddit.
ADHD 2.0 from Hallowel and Ratey is a pretty standard book.
That being said, there is no real replacement for medication when it comes to efficacy.
Have you tried a different medication?
I had to switch mine due to side effects and the new type has been working for me like a charm ever since.
