It is so refreshing to read a book like this. Most insomnia-themed books are horrifyingly perky, and full of the useless advice that all sufferers have found long ago on the internet, i.e. drink a warm milky drink and try leaving your window open (or closed). This goes into as much depth as is possible in a slender volume, and it is genuinely useful.
I liked the honesty of this. Cantopher doesn't promise quick fixes but suggests various strategies that work over time. He also debunks and warns of the dangers of some of the kookier remedies out there, and he isn't a proponent of pills and potions, on the whole.
One example: when identifying the cause of the sufferer's insomnia, mental health issues could be a factor. There are printouts of typical sleep patterns for those who have particular conditions. I have Generalised Anxiety Disorder, and the sleep pattern was spot on for me. Knowing this, I can make extra efforts to manage my condition if my sleep is out of control.
Perhaps the most helpful part, however, is the introduction. Since reading it I have changed my attitude towards sleeplessness, and my wellbeing has increased as a result.
I recommend this to other sufferers. I received it free as part of a Goodreads giveaway, but as those who follow my reviews know, that doesn't prevent me from giving a bad review if appropriate. In this case, it definitely isn't.
