Interesting interview, especially the part about pupil dilation being, on average, bigger in hppd patients. I've always believed that opiates/oids, while being highly addictive, can help hppd symptoms and dp/dr because not only do they drastically shrink pupil size but they also cause a flood of dopamine in the brain and anytime I've done them in the past I feel the dp/dr slip away as well as watching my visuals lessen quite a bit with it.
