Its hard to say if I had ADHD. I used to be a top student, then at 16 I started to feel unwell and also struggle with my studies, and I slowly developed chemical & food sensitivites around this time. I guess I could say at this point I developed what could be classed as ADHD + also anxiety. I struggled on for a few years and took up body building, and had improved health for a while but I was overtraining and ending up crashing, and it was at this point that I could say without doubt I had CFS. Just thought I'd mention though It might sound weird but having an orgasm increases my ADHD/brain fog for the next 4 days.
I have never been given any ADHD med, though I have asked for them. I tried the AD buspar which was ok/subtle. I really need coffee in the mornings to kick start me. Also love those (red bull type) energy drinks, but cant overdo them as I get too wired & my thoughts get scatty. I have a lot of trouble with remaining focused and also organising my tasks.
