some longacting benzos such as clonazepam are promoted to doctors as lasting 24 hours per dose
I dont think this is correct, the effective time varies a lot from person to person but, IMO, is seldom longer than 4 hours
so if having a very difficult day, a morning and lunchtime dose may be needed
dont take again before bed unless you cant get to sleep naturally
I am very against a dose daily before bed, as I dont think there will be much help the next day, and it may eventually stop you from being able to fall asleep naturally
remember that docs learn from their textbooks and drug company sales reps ,but not from anxiety sufferers
