🙏 Begin with prayer
Prayer is the first remedy, not the last resort. Whether you are facing this yourself, caring for someone who is, or simply reading to understand — here is a simple prayer you are welcome to make your own, in your name or in theirs:
Great Physician, thank You for N-acetylcysteine, and the way it can help thin mucus and ease each breath. Grant wisdom to use it alongside, never instead of, my prescribed COPD medication, and caution if I have asthma or take nitroglycerin. On the days breathing is hard, remind me that those who wait upon You shall renew their strength and rise up as on eagles' wings. Grant me peace with each breath, easy or hard. In Jesus' name, Amen.
“But they that wait upon the LORD shall renew their strength; they shall mount up with wings as eagles; they shall run, and not be weary; and they shall walk, and not faint.”— Isaiah 40:31
