This is very informative, who would have taught raising our pitch to balance the effect of dehydration on our speech was responsible for the messed up voice and not the alcohol. That's science, simple stuff are sometimes behind some complicated issues.

The poor alcohol all through would have been saying not me not me

Although I don't drink alcohol I have friends and family members who do who are always at the receiving end of this condition.

Now that I know, maybe next time I will tell them to lower their voice or keep quiet while partying that's if they listen to me.

Well done. This is cool and educative.
