lus control therapy aims to differentiate the habits that reinforce sleep from the habits that discourage sleep. According to Espie (?), there are six rules to follow.

Early on in the treatment the insomniac should expect to get out of bed many times during the night. Persistence with this technique is the key.

Sleep restriction aims to make deeper sleep possible by diminishing the time spent lying in bed without sleeping. The first step is to keep a sleep log to track how many hours are spent trying to fall asleep and how many hours a...
