My mother, 91 yrs old, has to get up 3 or 4 times in the night to ease herself. She is generally able to look after herself. Disturbed sleep every night leaves her tired and dull during the day. During the day and till she goes to bed, urination is normal. Any natural remedies? Or safe drugs? She is vegetarian and NOT diabetic. She takes LIPRIL 5 and Sorbitrate 5 mg as prescription drugs for her heart condition. Really need help. Thanks.
