Dear jbo,
If you really want to handle stress effectively, the first thing to do is to know precisely what it is! Briefly, stress starts with the person him/herself and has a definite cause. You can read about it in this article on how stress affects lifestyle:

When we experience stressful situations, depending upon how we deal with it, our bodies generate hormones so that we can physically deal with the stress.
This physical reaction comes from the days when we had to run for our lives from saber-toothed tigers! These "stress hormones," such as increased adrenaline, are only meant to be temporary solutions to the physical need for increased action! But nowadays, they are "on" almost all the time due to the higher levels of and different types of stress that we are faced with.
The best thing you can do is to learn what stress is and develop handlings that work for you. This article on stress management and relaxation provides some effective suggestions for handling stress:

As far as what can help with the physical aspect, in addition to good nutrition including sufficient water and regular physical activity, I've found valerian root to be extremely effective in helping me relax and sleep well. I've found a great product called "Snooze In" at the Vitamin Shoppe that is a combination of melatonin, valerian root, chamomile and some other sleep enhancing substances. I take 1 every night about an hour before I go to bed and it works fantastically for me.
All the best,
BB
