As for being out of control, in between getting absoultely hammered and being sober there are varying degrees of drunkness. I could see calling a state of being smashed as "loss of cognitive control", but when you're tipsy your inhibitions are lowered but not completely gone, and I don't know that I would call that a loss of control. It's an altered state of consciousness, that much is true, but there are a lot of things that put you in what could be called alterted states of consciousness. Concentrating really hard on a task or riding a roller coaster would probably have a bigger effect on my state of mind than getting slightly tipsy.
