how do you fix a phone addiction?

i want to get better at not checking my phone/social media/ youtube every time im bored or not busy or eating, especially doom scrolling. ive seen some people put restrictions on their phones, delet the app off their phone and just use social media on the computer sparingly. i dont want to completely eliminate social media, because it does bring me hapiness, but i want to be more present in my life, and be alone with my thoughts more
