My friend has been having trouble sleeping. Does the Satcharita mention if Sai Baba's Udi can help with insomnia?

Indeed, Chapter 33 of the Sai Satcharita contains two anecdotes in a footnote that specifically address the power of Udi to cure sleep problems. In the first case, a friend of R. Hari Sitaram Dixit couldn't sleep for eight days, even with a doctor's medicine. After being given Maharaj's Udi, he slept soundly through the night. The second story mentioned in Chapter 33 is about a child from Bandra who had not been able to sleep for two whole months. His father took him to Shirdi for Maharaj's Darshan, and on that very first night in Shirdi, the child got sleep and continued to sleep well from then on.
