Omg. I am actually really impressed. I'm a DSPS sufferer - for those who don't know it means my body just won't start producing melatonin when it should ... and then won't stop producing it when it should resulting a lifelong struggle to go to sleep (just not sleepy, even when exhausted), stay asleep ... or wake up!!! For past few years I have been using blue light therapy in the mornings - and this works too. It actually wakes me up. But going to bed was still a struggle ... I'm cautious about gimmicks so one day about a month ago I bought the cheapest blue light blocking glasses for evenings. And the rest is history. I'm typing this feeling Very Much ready for bed at 8pm. Unbelievable. Since starting to use these glasses in the evening it has happened three times now that I sleep so deeply I won't wake in the middle of the night, not at all - this is something that hasn't happened since my early twenties (I'm 50 now)! I am actually sleepy in the evenings - something I thought I needed to take 5mg of melatonin plus valerian drops or tablets to achieve. AND I actually wake up naturally!!! In the morning! NOT feeling utterly exhausted. Seriously, I didn't expect that. I expected a minor change - still struggling to go to sleep but a bit less, still waking at nights but going back to sleep more easily, still feeling groggy and struggling to wake in the mornings but a bit less, that's what I expected. Instead ... I am experiencing things that I didn't even think were possible!…
