Questions on Attachment, Entertainment and Pleasure

Forgive me if I write many questions in a single post, but these all deal with the thematic of attachment. I hope to quit my addictions to pleasures, **in major part social media**, by gaining insight through these. 1. What are Buddhist ways to deal with attachment to entertainment? (And in this context, aside from deleting the social media account). 2. Is it better to tackle this problem as - stemming mainly from attachment to pleasure in itself - or to tackle it as a question of a specific pleasure, i.e. social media? 3. How does diminution of the activity work best? Namely, should one - quit immediately - or quit in increments? If by increments, how does one proceed? 4. Does multitasking or combining sources of pleasure -- e.g. listening to music and chatting, or chatting and watching a movie -- intensify the detrimental effect? How so? 5. Would engaging in a single activity at a time, without multitasking or distractions, deter one from the pleasurable activities? In other words, does mindfulness diminish attachment? 6. Should one try to engage in replacement activities, or should one actively diminish the addiction? In other words, should one find substitute activities to engage in first, or is abstaining from media more important? Thank you.
