No simple way to track how a new medication is affecting my mood or sleep over time

My doctor asked me to keep an eye on my sleep and mood after starting a new medication, and the 'best' I could come up with was a notes app with dates. I'd like something that lets me log a quick daily mood/sleep score and then shows me a simple chart so I (and my doctor) can actually see if there's a pattern, without a huge health-tracking suite I don't need.
