It's a disgusting medication in my opinion. Once I was given 100mg by a friend, and stupidly I took it, not really knowing what it was. Slept from Sunday midday until 10pm that night. Waste of a weekend, plus I was severely dragging my feet on Monday at work. As Scagnattie said, it's good for sleep. If you were able to stay awake on it, I believe you would be far too groggy to enjoy the sedation. Apart from it being used in people with mental illness, I've since learnt heaps of ice users take it to enforce sleep.
