I can't afford it either right now and am trying to harass my sister into delving more deeply into her results, I will tell her about Snpedia, etc.

I found a nifty drug site called DrugBank, its technical but if you scroll down to enzymes it lists the cytochrome pathway for each drug. If you click on SNPs at the bottom of that part it will actually show polymorphisms....if you happen to have a gene sequencer in your kitchen you could test yourself! .

I've found some things that are suggestive even though I don't have hard data re: my genetics. It looks like there may have been a reason I took 2 prescription strength Prilosec and felt like I was poisoned.

Substrate=your med, what is being metabolized.
Inhibitor=lowers the amount of enzyme being produced to metabllize it.
Inducer=stimulates enzyme production.

You have to have the generic name and sometimes know which form you have.
