I have a similar story regarding alcohol. I think Mark said that there is actually not much formal evidence that alcohol is harmful - sure enough a big, expensive and up to date neuro rehab book I am currently reading does not even have alcohol in the index, despite going into great detail about the effects of all sorts of different substances, foods, hormones etc.

If it is really the case that people like us aren't being told about this because of a lack of research then some needs to be done pronto, since alcohol seems to have had such an obvious and hugely detrimental effect on so many of us, which we have had to work out by trial and error and to our own great cost.
