insomnia
"DO NOT take benzos for insomnia - they work great, until you reach tolerance, and then you go into full withdrawal unless you up the dose considerably. 



By then you probably will have already found the dirty underside of this terrible drug, which is agoraphobia, brutal insomnia, loss of motivation and stunning depression. Next, you'll find out that you cannot withdraw from this drug in a reasonable manner, and the required tapering-off methods could take years. During withdrawal you will have the worst insomnia imaginable, for months on end, and nothing will relieve it, except more benzos than any doctor will prescribe.



Don't even start on this evil drug. If you think this is an overreaction, Google "benzodiazepine withdrawal"."
