Describe the two instances mentioned by Hari Sitaram Dixit where people suffering from sleeplessness were cured.

In a footnote within Chapter 33, Hari Sitaram Dixit recounts two separate incidents involving the cure for sleeplessness. In the first case, a friend of his had been unable to sleep for eight days and found no relief from a doctor's medicine. Dixit gave him Sai Baba's Udi, and after taking it just once, the friend came back the very next day to report that he had slept soundly through the night. The second story involves a friend's child in Bandra who had not slept properly for two months. The father took the child to Shirdi for Maharaj's Darshan, and on that very night, the child was able to sleep and continued to do so every night thereafter.
