Glad to hear that the Equalactin helped with your attack!
As for the peppermint capsules, if you cannot afford them right now, why not try peppermint tea? It's relatively cheap and a good way to soothe your stomach before, during, and after an attack. That way you can get an idea how well the peppermint helps you. Granted, I'm pretty sure it is stronger in the capsules but if the tea helps even a little bit, you can probably imagine how well the capsules would work and perhaps save up some money to order them.
