Forgot one of the "main ingredients" for trying to avoid an obstruction!
Along with the other suggestions, take one of those over the counter gas
type capsules, such as Phazyme or Gas-X, as soon as you begin to feel
the pressure or pain. Just be sure that they are the Simethicone ONLY
type of med. The ones that have alot of other stuff in them don't work
as well.
Vera, thanks for responding. Sounds like you have had a really rough
time. I hope any of these ideas will help you the next time you feel it
coming on!
