I'm replying just because I have a bad feeling about PPI's. I have a bezillion things wrong in my GI tract, from mouth to anus; from life altering serious, to serious, to sensitive, to painful, to little pain, etc. I have used charcoal capsules for many years; helps with gas, air, nausea, cramping, etc....without causing anymore problems or nasty side effects. It is very important that you take the charcoal alone, not @ least 1-2 hours before or after any other product, the charcoal can hinder the absorption process for a bit. I am 65, I used to do whatever a Dr. said to do or medicine to take, I trusted them to be correct... but no more. When "idiopathic" is in too many diagnoses, that is a HUGE RED FLAG for me. Like I said I, know little about the real truth about PPI's, so, for me, it would take a lot of convincing to take them. You said "...not quite right ". I am still learning how, but that is your body telling you to listen to your body. Good luck with your hunt for answers.
