two things you might wanna check out:
the other is a herbal medicine called rhodiola rosea - do a google search to find out more. if you do decide to try it, then find a good brand with the right levels of active compounds. (i can't take it myself as it may contraindicate with the seroxat... which is proving HIGHLY difficult to extricate from.) the problem with the pharmaceutical industry is that they're not interested in things they can't patent. so there's less research on natural herb remedies. nonetheless many of these herbs have been used for centuries, so they've withstood the test of time in terms of 'cleanness' or 'quietness' (few side effects when on them and fewer withdrawal symptoms coming off them).
hope this of some use
