I have low potassium due to IBS and high cholesterol. To keep from taking a statin my Dr told me to double metamucil which helps both. I also take nexium, HBP med and xanax (3 times a day)for panic attacks/sleep but the metamucil seems to take these out of my body because now I don't sleep much, panic and GERD is worse. I alternate meds and metamucil 3 hrs apart and don't take it late in the day but not having much luck. Any ideas?
