Is there such a thing as self control? (Details Important)

This was a topic for my philosophy club that I unfortunately could not attend. A friend of mine also in said club argued to me before going that he believed there was no such thing as self control because it is a figment of our imagination, because for self control to exist there would have to be a self. The self what we often perceive as the self we most often relate to and make “decisions”, but ignore the other archetypes that reside in our minds.
I thought about it and its confusing complexity of what he was saying in bed last night this is what I came up with. I thought about how maybe we do not have any self control. We normally associate with out conscious mind or the mind that we can use and think with, when really there are so many other things going on in our brain at the same time. Our brains are so complex and make most decisions for us whether we think so or not. It is the driving force behind what we will remember what we will not, what we will in the end think, what is necessary and unnecessary. We do not have control over our brain the way we often think we do and our brain is compiled of essentially what we call our “self”, but we can not control all those complexities that co exist with our conscious mind. So really is there self control? Sorry for the long details =]
