John M.'s featured quote describes this specific detail directly: my breathing feels smoother, especially in the mornings.
Worth noting John M. doesn't claim all-day improvement, but specifically names mornings — worth reading that as a more precise, credible detail than a vague "I feel better overall" claim would be.
This site's own realistic-timeline table names "smoother morning breathing" as a realistic week 3-4 expectation — worth reading John M.'s account as directly consistent with that stated timeline.
