I have been taking apple cider as a supplement, but recently I doubled the dosage and the following night I developed severe stomach pains that have since migrated to my lower abdomen are. Is it possible I may have overdosed on vinegar, is there a home treatment option?
hai.yes  apple cider vinegar is a acid base fermented liquid containingsignificant amount   acetic acid and citric acid. it will cause stomach irritation and pain  in high dose.dosage will be depend on age,weight,indication etc.if you get acute  problem on your over dosage. be fix your daily dosage level. avoid taking it on empty stomach. acid in vinegar  will react to your inner wall of stomach and cause some  discomfort.you can take honey or yogart,or cheese to settle the problem.don't use vinegar untill you get the stomach problem solved.thank you hope i answered your query.
