Hate to be repetitive, but I'd still do a parasite cleanse.
If nothing shows up you lost not that much $ and will have peace of mind about it. The ingredients are just basically harmless herbs, from Humaworm anyway. "Die off" might happen, probably will if there are critters. Not fun, but it's a good sign in a way, that progress is being made toward better health down the way. I think Hulda Clark said GERD can be parasite related, too.
