Hi, My father is 54 years old and is a patient with weak heart (only 45% capacity). He has a weird problem where his legs start shaking when he falls asleep. At times it is so much that he gets up at night and is not able to get back to sleep. This problem was there even before when he had this heart problem. He eats tobacco and had water filled in stomach due to reduced heart capacity (as per what doctors told us).
