I'm learning so much about ADHD and possible causes. I'm pretty sure I have it since it takes me 5 times longer to focus on "boring" tasks. My oldest son has been showing stronger signs of ADHD and doctors are saying it's likely Autism Spectrum Disorder. Many of the people we have dealt with over the years made comments that were hints (without giving it a name)...such as teachers always pointing out behavioral and focus issues, anxiety (fight instinct), or the facial ticks... We've been hearing about it since pre-k and thought it was just his nature. 13 years later, the struggle continues.
Ok, enough of that selfish rant. Coffee snapped me into a hyper-focused state that allowed me to get through college. Unfortunately, more than 2 cups leads to heart palpitations..ugh.
