I just have to let all you people know that you aren't allowed by law to interfere in any way with your Mother's behavior. My Dad had dementia and wasn't allowed to drive after having a drivers test he failed. He kept driving around Ct to gamble for years and wanted to drive to Florida for 3 months vacation too. We tried to stop him and my sister even took him to court to keep him and the rest of the world safe from his antics.
We failed and the court ruled in his favor. Everybody knew he was lying about his behavior, but even with dementia he is ruled as competent. He kept right on driving vey badly almost until the end. We had to bail him out of so many stupid situations. Caregivers kept trying to tell us to "force" him to stop doing this or that knowing we couldn't. It fractured our family. Don't believe the hype - you have no rights over any of her behavior until she lands in a hospital.
