Hi sir I was not able to fall asleep from 5 days, I consulted with a doctor last week ,he told me to take zolfresh 10 mg for 10 days. After 7 days I stopped taking that and now from 3 days i'm not getting into sleep, whole night and day I stay awake, I don't feel energetic whole day and i'm not able to study bcz of this. I am doing exercise yoga 4-5 days a week. This is happening me from 3-4 years but I used to face this sleeping disorder sometime and it became worse. I am getting only light sleep, it doesn't feel like I slept last night, my body feels tired whole day will melatonin 10 mg help in getting sleep? I am 23 years old.
