I'm not very knowledgeable about benzos etc. But I have had some university training and work experience relating to physiological systems such as endocrine and neurotransmitters that I believe sound logical. Some of these developments focus on rebalancing physiological disruption in the body that can contribute to one's emotional state. My understanding is that a lot of research and development is currently being focused in this area, so there might be some new cutting-edge options you could explore?
