Yes, I've heard this before. I've actually experienced it before in the early days before I started cleansing. How many cleanses have you done?
I haven't had acid reflux now for 2 years. I used to take Tagamet every single day. I do think that OP draws mucus and stuff up. There is no doubt about that.
Personally? I'd actually change oils. Try anything else you have and see if the same thing happens. But for the most part I think yes, you are healing. I do think that OP contributed to my not having acid reflux anymore.
Do you take ginger during an attack? I keep some ginger candy around all the time just in case. 2 years ago I discovered it and it works faster than Tagamet. For me it stopped it almost immediately.
