Answer:
Limit your use!
Step-by-step explanation:
The best way to reduce anything in life is to limit exposure to the thing. Social media is no different. Many apps are specifically designed to hook your brain on them by utilizing positive reinforcement, most obviously in the form of recieving validation, "likes" or "kudos". If you can sort of wean your brain off of the dopamine rush you recieve any time you receive that validation, it will be much easier to put the phone down and reduce your screen time overall.
