To wake up early leave your phone away and add a reward
I discovered that temperature was a significant obstacle for me. The cold paralyzes me, making it hard getting up early. To address this as a phone addict, I leave my phone in the bathroom at night and I've programmed the bathroom heater for a high temperature to make it comfortable for me, even more pleasant than going back to bed. My reward is retrieving my phone and using it in a warm and pleasant environment. You can leave your phone near the coffee machine and treat yourself to a coffee as a reward. You need to find a reward that works for you, something better than staying warm in bed. I hope that helps you. 😉
