Honestly it depends. Sometimes they last for a few mins then at times last hours, or even a day. I have not found the root of my impulses, its just a strange feeling when you try to describe it. Actually you cant describe it, but it feels calm, relaxed but at the same time thinking and ready to spring into action. Like I said its strange. Now that I think about it, the cause of my urges are just as various. They don't just start from a particular instance.
