Once you take a sleeping pill to sleep you cannot really reverse it.
Although drinking some coffee or other caffeinated drinks may help you stay awake.
Still if you take a sleeping pill you should avoid driving or operating machinery until the sleeping pill has worn off.
Sleeping pills cause changes in the brain, and it takes a gradual process to reverse the damage.
Some doctors estimate it can take months for a chronic sleeping pill abuser's brain to be restored to its healthy state.
Those who have a severe addiction to their sleep medication often seek inpatient rehab.
If you accidentally took a sleeping pill by mistake then it could make you sleepy during the day so you should stay home if possible and avoid driving or if you do need to go into work take a uber, taxi or public transit.
If you did take a sleeping pill accidentally then you should drink some coffee to help reverse the effects of the sleeping pill.
If you wake up at 4am or during the night for no reason it could be that your hormones such as melatonin are out of balance.
Normally, at night time, melatonin levels will naturally increase, and cortisol (our stress hormone), will naturally be lower (than in the mornings).
If you are under acute stress, or you have been under chronic stress, you may notice that you tend to wake up between 2-4 am and have difficulty falling back asleep.
To fall asleep start by setting a bedtime routine.
Get into a bedtime routine and go to bed at the same time.
For example shut down the computer, electronics etc at the same time about 30 minutes to an hour before bed, then lay in bed without electronics and read a book etc.
Drink a glass of warm milk or take a sleeping pill to help you sleep.
Going to bed at the same time helps to get your bodies natural body clock to know that it's time for your body to sleep.
If you can't get to sleep your brain may not be shutting down for the night and keeping thoughts in your head or you may be suffering from Insomnia.
Sometimes stress, worry, thinking about other things etc can cause problems with sleep.
So if stress, worry etc are causing you to stay awake then you need to try thinking about other things.
You can also try using some white noise or leave the TV on low volume.
I find that having the TV on low volume helps me sleep as I'm thinking about what is going on from the TV and it pushes other thoughts and worries out of my mind.
If you're having trouble sleeping at night then you're likely suffering from Insomnia.
Your body may also not be producing enough of the hormone melatonin.
Melatonin is a naturally occurring hormone in your body that helps you sleep and when you don't have enough of the melatnonin it makes it hard for you to fall asleep.
So you may need to take some melatonin supplements.
Melatonin is a hormone primarily released by the pineal gland at night, and has long been associated with control of the sleep–wake cycle.
As a dietary supplement, it is often used for the short-term treatment of insomnia, such as from jet lag or shift work, and is typically taken orally.
Insomnia is a common sleep disorder that can make it hard to fall asleep, hard to stay asleep, or cause you to wake up too early and not be able to get back to sleep.
You may still feel tired when you wake up.
Most cases of insomnia are related to poor sleep habits, depression, anxiety, lack of exercise, chronic illness, or certain medications.
Symptoms of insomnia may include difficulty falling or staying asleep and not feeling well-rested.
Treatment for insomnia consists of improving sleep habits, behavior therapy, and identifying and treating underlying causes.
Sleeping pills may also be used, but should be monitored for side effects.

Reduce irregular or long daytime naps.
