Respected Hakeem Sahib, I am sending you spiritual practices as you asked for,

• If you cannot sleep nor have very less sleep then keep reciting these verses, you will soon go to deep sleep.

اِنَّ اللہَ وَمَلٰٓئِکَتَہٗ یُصَلُّوْنَ عَلَی النَّبِیِّ یَاَیُّہَا الَّذِیْنَ اٰمَنُوْا صَلُّوْا عَلَیْہِ وَ سَلِّمُوْا تَسْلِیْمًا ﴿احزاب۵۶﴾

• If you cannot sleep or have very less sleep then do ablution and lie on the bed then recite ayat al kursi once 33 times سبحان اللہ, 33 times الحمد للہ and 33 times اللہ اکبر, Surah Falaq and surah Naas one time each, after that recite these following verses.

لَقَدْ جَآءَکُمْ رَسُوْلٌ مِّنْ اَنْفُسِکُمْ عَزِیْزٌ عَلَیْہِ مَاعَنِتُّمْ حَرِیْصٌ عَلَیْکُمْ بِالْمُؤْمِنِیْنَ رَءُوْفٌ رَّحِیْمٌ ﴿۱۲۸﴾ فَاِنْ تَوَلَّوْا فَقُلْ حَسْبِیَ اللہُ  لَآ اِلٰہَ اِلَّاہُوَ عَلَیْہِ تَوَکَّلْتُ وَہُوَ رَبُّ الْعَرْشِ الْعَظِیْمِ ﴿توبہ۱۲۹﴾

 You will fell asleep during this zikr. (Book: Hayat us Saddariya) 

 I was suffering from insomnia and doctors prescribed tablets to get a sleep. As I read it somewhere and I thought that I will be edicted to those tablets and it will redude my memory too. Therefore I did the above amal and I get very sound sleep and it does not effect my prayers too. It requires your firm belief.
