I'm always confused why my experience never matches that of others in this arena. I run bare i3 and NeoVim. When I add Slack, Chrome and Spotify, I often see 12 Gigs of usage after a couple of days. Most of the time it comes down to Chrome's tabs... and Slack appearing to be leaky. I've recently started using an extension for Chrome which puts my tabs to sleep and frees the memory they were using. But still, I'm sitting at 8.33 Gigs of RAM used.
