Converted to Kefir — never going back
I switched to Kefir as part of a broader lifestyle change and it's been one of the easiest wins. The calm alertness was noticeable within a couple of weeks. Prepared in the morning it's genuinely enjoyable, not just functional.
The temperature of preparation matters more than you'd think — the difference between a mediocre and a great Kefir comes down to sourcing and preparation. Once you find your method, the consistency is satisfying. Wouldn't swap it.
