DXM can cure autism and OCD?

My daughter has autism and used to experience sudden emotional outbursts, sometimes crying for nearly 30 minutes at a time. To help prevent these daily episodes, I gave her 20 mg of dextromethorphan (DXM) with guaifenesin, hidden in juice. It seemed to help, but I’m unsure if the improvement was due to the DXM or simply part of her natural development as she grows older—only Dr. God knows.

I suffer from sexual OCD (obsessive compulsive disorder). I used to masturbate every night to relieve “the urge” and go to sleep when I was a teenager. The problem continued into my 20s and 30s until I discovered that DXM can “alleviate” my sexual OCD urge. Now I only masturbate once every 3-4 days and in my opinion, it’s better for my sexual health.
