Huh. My hiccup remedy has never once failed me:
- Sit upright, and ignore any hiccups till they're gone.
- 1. Inhale and exhale normally for a couple breaths.
- 2. Inhale extremely deeply, filling lungs to max capacity, and hold it (lungs full) for a slow 5-count.
- 3. Forcibly exhale steadily until lungs are completely empty, and hold it (lungs empty) for a slow 5-count.
- 4. Steadily inhale (repeating step 2).
If they're stubborn you may need to repeat the fill/empty cycle 2 or 3 times. 100% success rate for me and my family and friends. I guess the it helps relax the diaphram to take control of it and put it through its paces.
