Hypothetically, science proves free will isn't real

[Little lunch]

Personally, I believe that my sub-conscious is me. Just because it's in action ten seconds before I consciously make a decision doesn't mean that it wasn't thinking like I think I would think.
I make more one second decisions then I can count in a day.
That includes emotions.
It doesn't take me ten seconds to decide whether I'm happy, sad or angry about something.

Out of curiousity, if your sub-conscious is being altered, lets say through excessive alcohol, or involuntarily through drugs, or disease, or maybe Prozac type mood altering brain chemical changing stuff, do you still consider the things done under those circumstances to be 'you'?  Is there a scenario where you'd feel "That wasn't me" due to manipulations of your mind?

Yes, it would still be me. It would be the type of person I am under that sort of influence.
