How long would somebody live if their body became severely allergic to the H20 molecule?

I hope you realize that this does not further your point? It was already mentioned that there are certain aquagenic reactions of the epidermis (including urticaria, pruritus and acrokertoderma as the most common forms, though all being rare). It is also unknown what the mechanisms but the response is cutaneous and not an allergy to water molecules itself. Rather obviously as if water was eliciting a response, adding things to it like in juice or milk would not suppress it as others have mentioned. I have found an open access article that you may want to read: Wang et al. 2017 (JDDG  Volume15, Issue 6 Pages 602-608).

 

If it isn't water molecules, then what is causing people's throats to swell and blister? Maybe that could be confused for anaphylaxis. 

Also why aren't they reacting to their saliva, since we're told saliva is 99.5% H2O..

Where is the description about blistering of the throat after drinking? Your link only indicates lip swelling (which is actually unusual and seems to be a rather unique case). But it still a different surface than throats (which are mucous and have a lot of liquid on the surface).

As you said, if that was a reaction to water , saliva would do the same. In fact in folks with aquagenic issues, saliva and tears elicit the same response as tap water on cutaneous surfaces. The most likely explanation is still that it was something else.

Meredith - I wonder if you have heard of Munchausen’s Syndrome?

If not, I strongly recommend you read about it.

So Aquagenic Urticaria is not actually real, it's a made up condition?

of course it is real (if rare)  -  it's just not classed as an allergy (even though it sometimes gets called one -   wiki -   " It is sometimes described as an allergy, although it is not a true histamine-releasing allergic reaction like other forms of urticarial").
