ADD and things of this nature also stress me out. This stress for me turns into something immune. As a nutritionist for 4 plus years, and having a bro-in-law who has a clinic in Texas, I think it's important that you take a multi-vitamin /mineral to see if this helps. For ex. a Magnesium deficiency (e.g. [I]Natural Calm is available at Whole Foods) can correct any Mag. deficiency which controls water balance, and other not so uncommon but critical issues you have.
