This is something I've been thinking of doing myself. Often I use the internet far too much and social media takes up large part of that. It'd certainly be interesting to see how I would fair by completely blocking it out but from my lack of discipline, I don't stay away too long. I have now used it less and less though, trying to use it only for messaging rather than browsing posts. However this just means I'll turn to other entertainment online. I would say if you do wish to try stop using social media, do it gradually. Keep yourself from viewing too much at a time and maybe have a time restriction, and with every further use, decrease the allowed time. For me, a lot of it is just a waste of time, whereas I could be doing something more productive, so it's definitely good to cutback. Glad to hear you have realised that social media is draining and to do something about it.
