Stable income: Somewhat stable

The AI Sleep Optimization Service can be a moderately stable source of income for most people who try it. From my research and online sources, individuals may experience decent baseline earnings, but there can be some unpredictability in income from month to month. While some months may be consistent, others could show fluctuations. I'd rate it a 2 out of 3 because while there is the potential for regular income, it may not always be as steady as a traditional job paycheck.
