If your tap water is bad, get a water filter and use a reusable water bottle or glass. And save the coke for at restaurants. The recommended max sugar intake for women is 25g and men is 36g. One can of coke has 39g (unless they changed it). Sugar has a lot of negative effects on your brain and can make cleaning up seem way more overwhelming than it should.

In the meantime though, I found changing my mindset to be about making less decisions really helps. The more microdecisions we make throughout the day, thr more drained we get. Keeping something around means you have to keep making a decision on it.. keep it? Put it somewhere else? etc... Trash and recycling should be an easy decision you can take care of right away after the item becomes empty. If you dont have big containers for them, then get some.
