I've been noticing since I've stopped eating with meals, that I'm not going as often. Is this a sign of dehydration? I'm also not urinating as much. I usually drink the bulk of my water with meals, because it's hard for me to get down water when I'm not eating. Just wondering if anyone else has had this problem. I'm so constipated that I haven't gone #2 all day, which is highly unusual for me. I took Miralax, but I'm in pain from the constipation.
