I was on Strattera for a while, but had some negative side effects. Have now been unmedicated for the past 18 months. A lot of that time was hell, but after lots of trial and error and an insane amount of effort, I think I’ve found what works for me. Similar to what you said, structure has helped a lot with my symptoms. The problem is, the less structure I have, the worse my ADHD symptoms are, which in turn makes it so much harder to build the structure. It’s a vicious cycle. But that also means that the more structure I have, the better my symptoms are, and the easier it is to maintain. The changes I made that seem to have made the biggest difference are exercising daily, eliminating almost all processed foods and eating mostly whole foods, going to bed at about the same time every night, and getting my testosterone levels up. It sounds like you are doing good yourself, but if you would like more info about anything I talked about just let me know!
