Greetings and welcome to justanswer,
what is your age/sex?
How long are you feeling such day time sleepiness?
how long are you taking the drug?
did you consult a doctor yet?
Thank you for the information,
There are some common causes of such sleepiness.The common ones are sleep disorders, medications, shifting hours, hypothyroidism, hypocalcemia, etc.
As per the symptoms , it seems that you are suffering from the side effect of the drug ropinirole which may cause such somnolence and day time sleepiness on long term use.You may need to change to some other drug if your symptoms are not controled.
The other causes should also be ruled out.The treatment depends on the underlying cause.
