Never heard of anyone getting drunk on bread. Never heard of anyone beating his wife, his dog, his child, or killing someone after eating a loaf of bread. Never known anyone to be arrested for public drunkness or making an idiot out of themselves after eating a few slices of bread. Never seen any Scripture that admonishes man to "not even look at bread," however, the Bible does say that men should not even "look at the wine when it's red." Now if God has advised me to not not even look at it, I doubt if He approves of me drinking it.
Not in modern times. In the middle ages and prior, ergotism from eating bread was relatively common.
