tonib, my DW said something similar to that when I chose to stop drinking. She said "Well you should be able to have a drink every now and then". I think she said this so I would not be disappointed if I failed in quitting drinking, and she wanted me to be a bit less depressed about it.
It's put very well in Nonsensical's signature:
"People who can control their drinking don't have a voice in their head telling them they can."
