I'm in a new job which has required a massive amount of new learning and try as I might, I can't switch off at night. I toss and turn for hours on end and never get the restorative sleep I need. It's really getting me down and it makes me look haggard too. I often take paracetamol to make my body stop buzzing (which down-regulates the buzzing a bit but doesn't stop it). I was already a meditator, so I do this and practise breathing techniques but it's no good, I lie awake for hours on end. My job has me active on my feet all day, so I'm super tired come bed time. What can I do?
