I know it is a muscarinic antagonist but why does it cause drowsiness? What is the mechanism behind this?

Drowsiness can be caused due to overdose of Scopolamine.

I guess it is due to antagonism of M1 receptors in the brain which are responsible for wakefullness, maybe in the reticular activating system.
