We have a routine every night, and she gets plenty of light during the day. She get plenty of exercise and is still up. Tried Ambian and all that did was help her fall asleep (witch she didn't need help with) but she still was up over half the night. She ended up falling because all that crap did was make her dopey. I need something that will help keep her asleep!! She has dementia and uses a walker. We try keeping her up all day but that means waking her every five mins. Need help soon or I'm going to loose it from lack of sleep!!!!!!!!
