Change your sleep thoughts:
"If I awaken after about five and a half hours of sleep, I have gotten my core sleep.”
“I always fall back to sleep sooner or later.”
“I need less sleep than I thought.”
“My sleep is getting better and better.”
“If I get my core sleep, I’ll be able to function during the day.”
“I’m probably getting more sleep than I think.”
“Since I have survived nights of insomnia before, I can do it again.”
“If I didn’t sleep well last night, I am more likely to sleep well tonight due to a biological pressure to recover my core sleep.”
“Sleep requirements vary from person to person.”
“There is no evidence that insomnia causes health problems.”
“I am more likely to fall asleep as my body temperature falls through the night.”
“It is normal to initially feel alert if I awaken at the beginning or end of a dream, drowsiness will soon follow.”
