I find that people get both overly sensitive and paradoxically insensitive towards others when they are drinking, too.
I'm not sure if this relates, but two examples: One is a person I met in AA. Perfectly nice and polite and able to carry on long pleasant conversations when sober. I was at their house one day and he had relapsed/was drinking. Suddenly everything was an offense to him and he was super sensitive to things people said that weren't even insulting in the least.
Example two: I was at dinner with my cousin and we were having a nice polite, non intrusive conversation - until his fourth craft pint, when he started asking me incredibly insensitive and extremely personal questions that I would not answer for anyone, least of all a cousin I hadn't seen in 20 years. It was weird.
It wasn't me.
Being sober allowed me to see the two different Jekyll and Hyde personalities in these people when they drank.
