[Heber J. Grant]
In early years from the time I was made President of the Tooele Stake, when I had a complete breakdown and was a nervous wreck for six full months, and for 20 days after the nervous convulsion that caused me to be insensible all day long and could not lift myself up without assistance while lying in bed, I went to St. George to recuperate. I have gone to California time and time again to keep from breaking down completely because of insomnia. Thirty-two years ago I went to Europe, and I got a new lease of life and learned to take a nap in the day-time after my lunch, and today I am thankful beyond expression that I am in better health, can do mor work, feel better, sleep better than I did when I left for my mission. I have only had two serious attacks of insomnia since I returned from Europe. When I wake up not at 4 o'clock as I did yesterday morning and this morning, I try for a few minutes to go to sleep; failing, I sit up and talk to my dictaphone for two or three hours, then, I turnover and take a nap of an hour, sometimes of two hours.
