Fresh ginger tea works wonders. Put a piece of fresh ginger (peeled and chopped) in a thermos and pour boiling water. It relieves pain fast!
Instead of 20 minutes showering you can put a hot water bottle against your tummy.
And it's also cheaper for water use.
Having severe stomach pain? Take a cup of warm milk with a little nutmeg and possibly a spoonful of sugar. Stomach pain will pull away.
