Now, the title seems very vague but I have an issue about letting myself go. And by that, I mean out of my own lines of freedom. For example, I think way too logically at times, or I care sometimes what people think of me (insecurity), or just having fun and doing stuff that you usually wouldn't be doing. All these things will greatly help me if I can overcome, ...but these negative mindsets that have been hardwired into my brain since birth is a great wall to get past and I don't know how I should overcome it. Or even sometimes approaching 9's or 10's.

What helps you guys get in the mindset or frame?

I'm pretty much the complete opposite of all these traits when I drink alcohol. But who isn't?? In otherwords, how can I get my sober self to act like my drunken state? (And I actually have good game while drunk, despite all the people saying that liquor will affect your game negatively)

Well, your problem seems to be inner game. Why dont you read some posts or books on self confidence and inner game to give it a boost
