“Anxiety from insomnia triggers our fight or flight reaction and that’s not conducive to falling asleep.” – Dr. Leon Lack

There’s a particular kind of exhaustion that comes with fibromyalgia, the kind where your body feels completely drained, but your brain just won’t turn off. You lie there, waiting for sleep to come, watching the clock, knowing how much you need rest and feeling your body become more tense the longer it doesn’t happen. Over time, bedtime itself can start to feel stressful, like something you’re doing wrong instead of something your body naturally does.

What makes this even more frustrating is that the harder you try to sleep, the more awake you can feel. Worrying about sleep, thinking about tomorrow, and calculating how many hours you have left can quietly activate your stress response. Once that cycle starts, it tends to repeat night after night. Understanding why this happens can be incredibly validating and helps explain why sleep struggles aren’t a failure on your part, but a pattern your body has learned and can also unlearn.

Today, Tami is joined by Dr. Leon Lack to take a deep dive into insomnia and what you can do to start retraining your sleep. Dr. Lack is a sleep researcher and professor emeritus at Flinders University in Australia, who has spent decades studying insomnia and circadian rhythms, and his research has helped shape many of the behavioural treatments used for insomnia today.

In this conversation, Tami and Dr. Lack discuss what insomnia actually is, why common sleep hygiene advice often misses the mark, how insomnia becomes a vicious cycle, the different types of insomnia, the need to distinguish between fatigue, sleepiness, and tiredness, why conditioned arousal sits at the center of most insomnia cases, pros and cons of sleep medications, the difference between acute and chronic insomnia, how circadian rhythm disruptions contribute to insomnia, CBT-I and why behavioral strategies are often the starting point, sleep efficiency training and how it helps consolidate sleep, using melatonin and morning light to support circadian rhythm and sleep timing, options for accessing support, and more.
