Hi Disturbance of sleep can be part other disorders.. We need to treat underlying cause before addressing sleep it self.. For that we need your history for which you have been prescribed medications...and how long it's been your taking and how much better ur symtoms vise..? According to what you mentioned your able to sleep for 8-9 hrs but falling asleep n quality of sleep are not good...

I went through your prescription. I think a bit of dose adjustment will help fix your sleep. I would also like to know if sleep is the only issue or are there other symptoms as well which have been bothering you. You can also follow sleep hygiene practices to enhance your sleep. They are a list of dos and donts that can be followed easily.
