I suffer from Insomnia occasionally as well and sometimes I need to take some sleeping pills and when that does not work I take some Vicks Nyquil which really puts me to sleep.
I try my best to avoid the use of sleep aids to sleep but sometimes I have no choice because not getting enough sleep or any sleep at all at night can make it hard to function the next day and also make you unhealthy.
Although sleeping pills and other sleep aids may be bad for your health the lack of sleep is worse for your health.
To try and treat insomnia though without sleep aids try going to bed at the same time each night, avoid caffeine and especially coffee for 2 to 3 hours before bed.
Avoid alcohol, cigarettes, and heavy meals in the evening before bed and then try and make your bedroom as dark as possible.
Sleeping in the dark helps your body adjust to nighttime and tells your body clock that you need to sleep.
But sometimes you will have to take sleep aids whether over the counter sleep aids or prescription sleep aids.
