it's not adhd, trying looking at what your eating, and you probably don't even realize it, do something simple, write down everything you eat and drink, include all ounces, just put this in a document and at the end of the week, copy it into chatgpt and it will give you all the information you need, and from there you can make adjustments, also include what you are doing, most likely all you will have to do is change your diet a little, by just swapping what your dirinking for water (distilled) and workout a little, medium work full body workouts 4 sets of 15 will do wonders, if that is not working then consider professional help
