Didn’t know that! Saving it for future reference.
Another thing you can oftentimes do to fend off an impending GB attack is to drink water, lots of it. When you feel the first unmistakable symptoms of an attack, drink 16 oz of water. If symptoms don’t subside in 5 minutes or so, drink another 16 oz.
I’ve never had to go beyond 32 oz total. There is a danger of drinking large amounts of water in a short time period, so I hesitate to do more than 32 oz that quickly.
It usually works for me.
Not medical advice. YMMV.
