Genetic differences in response to medicines

There is this interesting research article about aspirin and migraine:

http://news.bbc.co.uk/1/hi/health/8617254.stm

whichin itself is worthy of consideration.
Mind you aspirin is so bad for my stomach I could not use it too often.
Still I was told that we need to alter our abortives as much as possible in order to prevent MOH, so this is extremely useful thing to know and I mean to try it. I suppose in the past I tried too small a dose to have any effect fearing the stomach pain.

However what interested me most in this article was that for one the Doctor admits openly that:
"Different people respond to different drugs in different ways, and at different times." Great!

At last, we have the admission, of the obvious.

This is serious research and good to know that migraine treatments are being constantly investigated, so I would not dismiss it too easily. I like to give ideas a chance before I make up my mind.
