Protracted Acute Benzo Withdrawal

I am in PAWS (protracted acute withdrawal syndrome.) Today, I was having some PAWS anxiety, and I came across an interesting article:
https://www.medicalnewstoday.com/articles/320637. It discusses Dopamine. I decided to give the Velvet Bean (Mucuna Pruriens) a try and wow! It really relaxed me so much! I even felt like taking a nap. I guess I could say that the sleepiness is a side effect. However, it did make me very sleepy, and I believe that if it were taken in early evening hours, it could certainly help with insomnia. Has anyone else tried this supplement yet?
