Caffeine disrupts the quality of sleep even if you are not aware and feel like you are sleeping fine. I'm not saying this is the cause of any issues you have, but just want that to be considered. Attention and focus have strong correlations with sleep quality. I say this as a fellow "ADD-er", and only point this out because, being in the health field, I see so many people who completely neglect proper sleep hygiene and then wonder why they feel like crap all the time. This makes me suspect that most of the population has no clue how important proper sleep is to quality of life.
