I would go the herbal way, There are tablets and teas like st johns warts and genseng for those down times. Then you would need some for the 'up' ones. Such as chalomile, hops, lavander or lemon balm.
I am really into Chinese medicine. http://www.ehow.com/about_5727973_chine ... order.html
On the same line. The above link is a chinese herbal advice but they oftern use acupunture too. If accupunture is too expensive or not your thing magnets are said to have the same effect but slower! I would advise this book which is very cheap.
The Practical Guide to Magnet Therapy by Peter Rose
Of course I am not a Dr and can't advise you to stope meds or that any of this will certianlly work but I am a beliver in things like acupunture.
