Hi Tracy Lee, thanks for your question this is such a great find! I'm glad you shared it with the community, it's important for everyone to be aware of new research and findings. I liked this quote at the end: "Doctors should consider this if patients are not responding, rather than just increasing the dose." It's definitely important for doctors to be aware of each patient's history rather than increasing a dosage. I'm interested to hear: what are your thoughts about this study?
