^ oddly enough oversleeping can result in me feeling like crap or even have a minor cold upon waking up in some cases, but I'm weird when it comes to sleep. A raw fruit based diet seems to change sleep requirements. But anyways, one of the best ways to prevent getting sick is the good ol' "let thy food be thy medicine" axom... Transitioning slowly to a raw plant based diet high in approximation to what we ate for millions of years in the african tropics (we call it "fruit", but really it's the unimaginably complex biochemical sexual reproductive organs of flowering plants) seems to jive really well with me personally if done right. The studied medicinal benefits of plant foods and medicinal fungi are increasingly off the charts (harmalas as well), which is compounded by the fact that due to generations of eating junk we're probably chronically deficient in a range of things.
