I recommend the following experiment for those still concerned about azeotropes:

Probably the oldest commonly used azeotrope in human history is derived when distilling ethanol from a solution of ethanol and water. An azeotrope of 95% ethanol and 5% water has a lower boiling point than either, hence is the most concentrated form of ethanol attainable (without an extraction involving benzene, I think it is).

Acquire a quantity of said azeotrope. Injest small amounts, perhaps blended with any other aqueous solution preferred. Continue injesting until either: 1) a deep understanding of the problem is acquired or 2) a deep indifference to the problem is acquired.

Report on the results of your experiments so the data can be verified and independently confirmed by similarly scientifically-minded individuals.
