I am about as ADD as anyone I know and to top that off have terrible sleep habits. I am trying to finish up my doctorate and am having to take some ridiculous classes. Studying for tests while working 40 hours a week is tough. It seems like the older I get the harder it is to retain information. Long story short what's available (either product or component) that may improve cognitive function (memory, clarity, etc.). I looked at bottled oxygen but I am not sure how long the effects are for. Might be funny going in to take test with a bottle of O2 lol.
