My BMI is perfect, i never eat sugar or junk foods, i cook all my own, mostly veg and lean meat etc. and i work out. i have never been ill. I am 66 and i do have chronic insomnia. I can't help my insomnia after many years of trying, could this be the cause? what can i do? my bloods also showed up boarder line for kidney and liver functions, so as you can imagine, my anxiety levels are through the roof,and i cant see my GP for another 3 weeks ( Help)
