SAMMY’S SLEEP SAVER:

QUITTING THE ZONE I obey the 20-minute rule, which is that I never stay in the sleepless zone for longer than 20 minutes. Instead, I force myself to get up, make my bed and go and do something light like read a magazine article or make a cup of chamomile tea. I then return to bed with a different head space as I know that I can get off to sleep again. Find more Sammy Margo sleep wisdom at thegoodsleepexpert.com
