Need help falling asleep without sedatives

Hi y’all. I have been having troubles sleeping. I have troubles falling asleep. Occasionally I’ll wake up in the middle of the night or super early (right now, it’s 5:15am…) I started working out and stopped taking my Trazodone at about the same time, and I’m not sure what’s causing the troubles. I workout before 2pm, so it’s not like it’s right before bed. I stopped taking Trazodone because I was sleeping excessively and was still exhausted the next day. My psychiatrist wants me to go back on Trazodone but half the dose I was taking. I really don’t want to go back on a sedative. I’ve been putting down my phone before bed and reading. I also don’t have caffeine after 1pm. Does anyone have any suggestions to help me fall asleep or any natural sleep aides that aren’t melatonin because that makes me feel worse the next day than Trazodone?
