Who was the friend of R. Hari Sitaram Dixit who was cured of his inability to sleep?

In the accounts noted by R. Hari Sitaram Dixit in Chapter 33, there was a friend who suffered from severe sleeplessness. This friend approached Dixit at his office, explaining that he had not been able to sleep for eight days and that a doctor's medicine was having no effect. In response, Dixit gave him some of Sai Baba's Udi and instructed him to take it for three days. The very next day, the friend returned to the office with joyful news, reporting that after taking the Udi the previous night, he had slept very well throughout the entire night, demonstrating the immediate and potent effect of the sacred ash.
