How to get the open mindedness that alcohol goves you.

So been drinking a while. Usual standard weekend stuff. How do you get that feeling sober? Theres a part of your mind that alcohol opens up. Like MDMA, Shrooms etc. It is in you to feel that way. Its all in the mind, it opens it up. We as humans only use a small part of our brain doing day to day tasks. But things like alcohol etc, open up the parts that we dont use. The below photo according to google, says the 10% usuage of our brains is false, which definitely isn’t true due to when we drink or smoke etc…. But when we take substances, alchol etc mentioned above. We do not feel the same as we do without. This has to be something that is unlocked within our brains. Im not technical or anything but all that we are is the brains in our heads. Realistically, thats all that we function on. A body which functions from the main source, in our heads. So how can we not unlock the feelings we get from alcohol and drugs sober? Its there everyday, same brain, one body. How can we not reveal the secrets of confidence, desires, dreams etc sober? A substance changes our thoughts, how can we not acess them. Without the alcohol or anything else above? How do we find that unlock mechanisim to believe in what we want under the influence of alcohol?

Would love some good suggestions or scientific knowledge. This is not a cry for help please…..but its there obviously…or are we not that advanced that we don’t understand how it works…..if thats the case we are far behind…..
