I will just make a few final observations and sign off this chain. 1) Nobody is forcing you to do anything you don't want to. 2) I was merely sharing some useful Science which IMO has as yet not seen widespread adoption. 3) Our immediate environment will not change to accommodate our specific needs due to economic concerns. Due to globalized nature of work people are working longer hours and all times whether night or day. If my job which i need for survival needs me to stay awake at night i need to find means to adapt myself to it without ruining my Health. Research is showing more and more that Sleep is foundational to everything else and hence i need to treat it seriously and with high priority. 4) You are making a lot of assumptions/conclusions without having looked into the Science which i think is wrong. While DSPD is a thing it is not fully clear whether there is a genetic component to it. Also Epigenetics is a thing. 5) Finally, if the situation were reversed and i were suffering, i would do everything in my power to study as much as possible on available Science, Traditional Methods of healing etc. to come up with some plan to manage it with/without a doctor. You will find accounts in the popular press of people suffering from something which the doctors could not diagnose properly but they never gave up and kept researching by themselves and trying out new things until something worked for them (usually after consulting with a doctor on it).
