When I can’t sleep, I turn around and sleep “upside down” - moving my pillows to where my feet were beforehand, and my feet to where my head was beforehand - and I stick with that for a week or so. It gives me a week or so without insomnia and then wears off, so I have to turn myself back around for the next 7-12 day period.
Admittedly this could just be a me thing, but let’s put our faith in this method and let the power of placebo effect take hold. Boom, minor bouts of sleeplessness are cured.
What are your own examples of this?
Btw, if tea is too bitter for you, rooibos might fit better. Plus there are all kinds of herbal ‘teas’, or rather mixtures, that don’t contain tea proper — at least where I live. Although tea itself has barely any bitterness if you use a smaller dose of green tea, or something like white tea.
Of herbal or aromatic teas, you might want to choose those with berries or flowers, since they impart some sweet flavor, but still far from the sweetness of fizzy drinks. A bonus benefit is that there are a lot of different flavors. One should take from life all that it has, after all.
