Oh yes, forgot to mention, my grandmother is in the hospital. They don't know what's wrong right now, but are running tests. My dad is worried that it could be congestive heart failure (she's on statins, has had at least one heart attack, a couple of stents put in, and has a pace maker). She was feeling better on Sunday than she did on admission on Saturday, but that's probably because she was dehydrated and her electrolytes were depleted. I really don't think she should be living on her own anymore, she does not hydrate herself. My dad is worried.
