Last season, we met Clarence who spent several years in jail for a crime he did not commit. Following his exoneration, he developed PTSD and we sent him to see PTSD specialist Dr. Eugene Lipov.

Dr. Lipov pioneered a groundbreaking treatment for PTSD which involves a simple epidermal injection to the neck. He is often able to stop the symptoms of PTSD with one shot and he says the brain is rebooted to a pre-trauma state. Dr. Lipov treats both Clarence and wife Molly, who says she is experiencing secondary PTSD.

Just 30 to 40 minutes after receiving the treatment Mollys says, "I don't feel anxious anymore" and Clarence says, "I feel like a weight has been lifted off of my back and I'm just looking forward to a better life."

Joining ER physician Dr. Travis Stork and clinical psychologist Dr. Judy Ho on stage, Clarence says he is in awe of all the benefits he has experienced following the injection.

"My mind doesn't race 24/7. I feel a lot better and a lot more confident," he shares. Molly says the treatment has improved their relationship as well. "He's the person and the husband I've always wanted to have," she adds.
