That's funny, my husband also swears by pickle juice as a quick remedy for cramping and dehydration -- something about all the sugars and salts in the juice helping to balance your electrolytes. Of course, that was a remedy for exercise recovery, not COPD cramps, so it might not work for everyone. And it's important to note you shouldn't have too much pickle juice -- a few sips is plenty, like you said. It's so interesting for me to hear someone else talk about this! Glad it helps you. -Melissa, copd.net team
