Glad to hear you're feeling better! I've also experienced sensitivity to light and irritation with loud screaming children in public. Okay, the latter always bothered me, but still. I don't know if I've had the the Twilight Zone feeling, but I have felt like my body was drunk (being clumsy, losing balance, feeling like things were going in slow-mo at times) but my mind was sober. I guess that's sort of Twilight Zone-ish? I was alarmed but then I read that it's normal with withdrawal. It'll go away.
Btw, your thread title brought me back to when I was playing GTA: Vice City. I used to get in my car (or someone else's car) and drive around just listening to the 80s music. Good times.
