Who's calling? <a href=" http://www.greatnoiseensemble.com/xanax-for-agoraphobia/ ">half life of xanax</a> Leicestershire police have launched their annual Christmas campaign against drink-driving (see page 20). Over the next month, officers will be stopping drivers they suspect of being over the limit at random locations at all times of the day and night. And they have warned motorists to be aware they can still be unfit to drive the morning after their last drink.
