"caused an annoying case of hiccups. It’s been a long 
     time since I’ve had to worry about two days worth (or 
     more), and hopefully, they’ll go away soon"

I take it that most people shouldn't be worried about this specific outcome?

I think every paragraph has a sentence that explains this to avoid silly comments like this.

These symptoms resemble people's experiences when they go dairy-free. Soylent isn't designed to be hypoallergenic, IIRC, but it does eliminate some commonplaces that are in standard American diets.

Very interesting, of course it only means something if there's someone else experiencing the same thing.
