DXM decreases sensory inputs from the environment and increases my awareness of the surroundings, neuroplasticity?

By robotripping with DXM, the summer heat no longer bothers me like it used to, I now have greater tolerance for sensory inputs. DXM also changes my brain by making me more open-minded and aware of my surroundings. My attention to detail, patience and tolerance for annoyance also increase with an overdose of DXM. Thanks to DXM, I’m no longer depressed and I now love eating fruits and vegetables more than carbs and meat. “Abusing” DXM truly makes a difference in my brain and my way of thinking or is it because I age and mature? Only Dr. God knows…
