GABA is Gamma-aminobutyric acid. It is an amino acid and the chief inhibitory neurotransmitter in the central nervous system of humans. It helps induce relaxation and sleep. It also acts as a balancer for the brain where excitation of the brain is balanced with inhibition.
Most herbal sleep aids include it. It's good stuff.
Melatonin is also a great relaxation/sleep aid.
You are right that you can't fix it for him. Setting some boundaries, being patient with him, and letting him work through his issues might result in a more mature and wonderful H. Only time will tell I suppose.
