Previously, i used to experience delay in sleeping once a week. Last week a day i slept for 3 hours and next day I couldn't sleep at all. Following day, i consulted my family doctor and he suggested to take nindra .5mg with revamp for 4 days. Today is the 4th day of medication and I experienced sudden wakeup in the early morning and the sleep lasted for 5 hours. Not sure whats the issue
