Don't underestimate the role of depression/anxiety in the way these feelings manifest. I've dealt with a lot of the same "foggy" feelings and definitely felt disconnected, almost like euphoria. These are scary things to deal with as you also fight for your sobriety. Being off meds is fine if you don't need them, but there are many different types that react differently with your body. I've had great success with them during my darkest times, and also I've had some that sent me into panic mode.
Taking care of your mental health and the chemicals in your brain will make staying sober much much less of a mountain to climb.
