If you decide to search the net and find a possible alternative to med's might I suggest truehope, I am bi-polar and am taking it I noticed more stability right away I am not completely stabelized but much much better than the drugs did and none of those awful side effects. The longer your on drugs the more your body has to detox or get rid of so as your detoxing your having the same side effects. You don't stop your drugs you work with their support calls and evaluation forms you fill out everydayto keep track you cut back on med's only when your evaluation charts stabelize and you feel you need less and less med's to stabelize.
Even if you don't want to try this out you can still print off the evaluation forms (bottom right of screen) these will help him see just how he's stabelizing on his med's and help you to understand the symptoms of bi-polar. Really its worth it for both of you.
The stories of how this came about are very interesting and for some of us it makes sense that mental disorders are from a lack of something or another, our bodies are our best doctors if we fuel them right and give them what they need. For some this sounds absurd, those who rely on doctors more sor than naturalpaths or alternative medicines.And some think large doses of vitamins and minerals are dangerous but the studies show that people with bi polar are lacking large doses of these minerals and eventually you cut back to a maintenance level. The side effects of vitamins are much less scarry than those of lithium for example.
Just thought i'd give you an alternative to look at while you haven't tried too many med's yet. Good luck to both of you!
