Copilot's default behavior is stupid. You can turn off auto-suggest so that it only recommends something when you prompt it to, and that should really be the default behavior. This would encourage more thoughtful use of the tool, and solve the fatigue problem completely.
In IntelliJ, disabling auto complete just requires clicking on the Copilot icon in the bottom and disabling it. Alt+\ will then trigger a prompt. I know there's a way to do this in VSCode as well, but I don't know how.

I dug into this a bit, since I want the same functionality, I found I needed an extension called settings-cycler (https://marketplace.visualstudio.com/items?itemName=hoovercj...) which lets one flip the 'github.copilot.inlineSuggest.enable' setting on and off with a keybind.
Not sure who's in charge of the Copilot extension for VS Code, but if you're out there reading this, the people definitely want this :) Otherwise of course, your tool rocks!
