"i was hopeful this medication would help me with insomnia, but have had a mixed experience. at 0.5, i get very sleepy but don&#039;t necessarily fall asleep. it does last long which helps with morning anxiety if you take it at night. i do find it helps me to sleep if i pair it with an antihistamine (i use hydroxyzine, under a doctor&#039;s prescription, 15 or 20mg). so clonazepam is a decent anti-anxiety medication, but i  didn&#039;t find it to be very helpful (alone) as a sleep aid."
