I had Hiccups for over 10 days continuously, went to see a doctor but doesn't helps, so went to another doctor giving me the same comment. I almost die because I cannot breath properly.
This is a true story. Apparently, Magnesium tablet or powder can help. My Pharmacist is better than those stupid GP. Never trust them quack they don't know their stuff.
My diagram muscles could not relax, later causing Reflux. Where the stomach acid came up and burnt the top chamber. It was very painful and hard to breath. This is very serious.
Next time when you see a person having continuous Hiccups, tell them to see the pharmacist for Magnesium tablets. It will helps, it is because I believe I drink too much coffee, that stop my daily intake of magnesium from my meal. Lack of magnesium supplements can cause muscle cramps that what it is.
