2 x Health Related Articles Needed ASAP

I'm looking for 2 feature length health related articles:

1) The science of a Hangover – what they are/ causes/ physical processes etc.

2) Avoiding a hangover – discussing ways of avoiding/limiting the effects of a hangover – will include legitimate proven techniques, misconceptions, foods, medications, ritual post alcohol behaviours etc.

I'm wanting these to be feature length eg. somewhere around 2000 words each, written in a relaxed but informative and casual style. I'm not looking for anything too formal or 'stiff' but interesting to anybody who is reading it. It's to be used on a self help website (just so you know the direction). Obviously researching is absolutely fine but it does need to be original writing and pass copyscape without fail.

The candidate MUST have excellent english, so US, UK, AUS writers preferred.

The deadline is the 9th of this month and unfortunately can't be moved. Please let me know if this is of interest as soon as you can and I'd like to see an example of your writing style please.

Thanks guys

Gary
