Where a situation arises when you cannot not sleep, I will recommend you to Pray and not to take and form of sleeping tablet or solution.

Prayer, which is saying what God has said about a particular situation  is the most efficient and best practice tool from experience and from testaments of many Christians.  I will however write of my experience:

I could not sleep about 6 years ago and I was taking sleeping tablets.   After sometime, the tablets did not make me sleep if when I took them.  I could not sleep and was so frighten.  I went to a chemist to buy some more sleeping tablets and on this occasion met the owner who was a pharmacist, female and Christian.  I don’t know why she told me what she did as it was her business.  She said to me “Are you a Christian?”  I said I was.   She told me that once I start taking sleeping tablets I will not be able to stop and it was just a tool of the Devil to get me addicted, then get my  mind messed up and eventually which his ultimate assignment would be to draw me away from God and the destiny that God has for me.  I believed her.  I went home and really prayed.   I slept like a baby till the next day.  I have never taken any form of sleeping tablets/solution ever since. My sleep is beautiful now. 

2 years ago I lost my late husband (RIP). I was in such shock I could not sleep.   I was taken to my GP (Doctor) who said I was in such a state of shock and that is why I could not sleep.  He said he had to administer something to make me sleep.  It could have been easy at this time but I remembered how God made me sleep in the previous experience.   All aunts & well wishes felt the same as the doctors in this particular instance (even though Christian).  I did not take the tablets.  I said my usual OKAY GOD, YOU PROMISED ME SWEET SLEEP!  I was fine.

Please pray and remind God of his word.  God has exalted his word over even his name and his word is YES and AMEN (so shall it be).  His word cannot lie.  These 2 verses I look at and meditate and then I go to bed like a baby.

Psalm 4:8
I will lie down and sleep in peace, for you alone, O LORD, make me dwell in safety.

Proverbs 3:24
when you lie down, you will not be afraid; when you lie down, your sleep will be sweet.

So please get a bible and begin to search the word of God and you can email me if there are other problems. 

Note:  Christianity is the act of accepting Jesus Christ as your lord and saviour and acting what the bible says in faith.   There are no side effects.  You will live a life full of bliss and happiness and even when the trials come his word will be there to see you through the situation and you only come out stronger and more in touch with him.  The bible is a manual for your body, please use it.
