"i have had insomnia related to anxiety for about 6 years,  exasperated by shift work and taking citalopram. took me ages to fall asleep (some nights couldn&#039;t sleep at all and this induced panic attacks) and waking atleast 3 times throughout the night. finally referred to a sleep disorder service by nhs (uk) and my consultant prescribed this at 15mg. i fall asleep within an hour of taking usually. it has really helped! feels like a nice natural sleepy state and not overly drowsy like you can get with sleeping pills. reduced amount of times i wake also. however, i now have cold sweats every morning which wakes me up, they start from around 6am and continue till i wake up. going to see my doc about this as they are becoming unbearable."
