I agree completely - I've been using social media less and less, and have found myself to be happier in turn. The "feedback loop" is seriously a real thing, and it just gets worse and worse really!
I like your analogy to alcohol though - because especially as a media artist, social media management is a necessity. A glass of wine in the evening is enough! ;)
Definitely - I think social media is there to be enjoyed and dipped into now and again, not something that takes over your life. Just like wine :)
