Drunk dialing

[2] In Kurt Vonnegut's 1969 novel Slaughterhouse-Five, the main character describes his tendency to drunk dial: I have this disease late at night sometimes, involving alcohol and the telephone.

[8] Although the breathalyzer function was incorporated to help the user assess fitness to drive, rather than fitness to phone, the owner can program the LP4100 to restrict calls to specific telephone numbers on certain days or after a certain hour, a feature that might help limit drunk dialing by eliminating calls when the user is more likely to be intoxicated.

Some reports indicate that this phone, or a planned future version for U.S. release, would activate the call-blocking function in tandem with the blood alcohol content results from the breathalyzer.

Drunk Mode prevents users from calling or sending messages to specific contacts for up to 12 hours.

A reported feature also sets notifications every 30, 60, 90 or 120 minutes to remind users not to engage in certain "drunk behaviors".
