No, it's not lost on me that I admitted to previously consuming 3/4 of a gallon of Monster a day two comments ago and now I'm posting about shitting blood, but I think there were other contributing factors (notably bad lifting technique).
Edit: More on topic, if I don't care about the yes/no checkbox of whether they think I have "ADHD," and I don't want to get on the medication (which I've tried, informally researched, and made a fairly informed decision about), what can professional advice provide me that internet research about symptoms and ways of coping with them can't?
May be pure coincidence, but in my case the former was causing the latter. Through trial and error I discovered that zero caffeine intake completely eliminates my symptoms.
I know you didn't ask me, but as somebody who just realized he could have a mental illness, the thing that terrifies me most is being branded. Technically, on the books, ADHD is an incurable mental illness. That means, once diagnosed, you're forever mentally unstable in the eyes of both the law and potential business partners.
I doubt I'll bother to get officially diagnosed. The risk is too great and the upside too small. I've been coping this long with it and now that I know what I'm dealing with I can find ways to cope with it even better.
