I have been taking 5 HTP (non time release) when needed for sleep for 15 years. It helps with my overall mood too. But my health went into downward spiral 3 years ago. So for me, the tryptophan/serotonin mechanisim is not the cause of my ME nor the reason I still have ME. Many people in the general population suffer from depression, but they don't have ME.
I am grateful to hear about new research, but my preference is to focus it on what treatments will improve the core ME symptoms (IOM report, especially PEM). We need greater collaboration among doctors that have treated severly ill patients (ME or closely related biological dysfunctions) to decipher what the severely ill patient 'big data' means.
I worked with data for 20 years. Having more data is not always helpful. Data must be organized and structured in a way that is meaningful. This is why seasoned health care providers with severely ill "hands-on" experience need to be assembled.
I appreciate this thread and being able to express my opinion. But I can't ignore the knowledge I gained in my career and what I have learned about ME.
Thank you for reading this.
