Re: Nausea abdominal pain & peppermint extract
Next time you get abdominal pain, think back to whether you ingested acidy stuff (such as orange juice) or especially acid together with starch (even vinegary pasta), or tart-tasting tea, or Oreos which is a harsh form of chocolate.
AVOID peppermint as this causes alot of acid reaction. (you might try spearmint which is milder & less problematic).
ABOVE ALL, eat cherry yogurt or Bing cherries. I'd be very surprised if this doesn't give you relief.
