I was like you, the transition was not easy, but what helped me was to brush my teeth when I already went to the bathroom to pee. This meant that I rarely brush my teeth at the same time. But I do it every night now. This also helped me reduce my snacking after 20:00. Because I didn’t want to snack after brushing my teeth. I convinced myself I was going to do this and ever since I only missed 2 nights. What also helped is using a tracking app where I could check it to “gameify” it.
