Love this book! Motivating and practical. Easy to stick with. The day by day structure made the simple changes feel manageable.Simple steps that lead to meaningful results over time. I’m already sleeping better and have more energy.
This book is practical, hopeful, and extremely easy to followThe daily format layout makes real changes feel doableThe authors writing is clear, compassionate and surprisingly very motivatingSimple steps that are outlined made a big impact over time My sleep and energy started improving in just a couple of weeks!
If you are willing to do the work these practices really work. I started my journey at the end of May and within weeks I was sleeping a bit better. I didn't have to make too many chances since I already exercised daily and I was on a plant based healthly diet.The biggest change was leaving my phone downstairs at night and setting aside only a few times during the day to answer emails.. Once I got out of the habit, I moved on to another suggestion. I walk after every meal, get day light first thing in the morning and keep to a scheduled bedtime. I feel amazing and it wasn't that difficult. You

I found this book to be very helpful. This Doctor brings science and every day practice to real life and helps you regain your vitality. I strongly recommend it to anyone at any age or stage in life. Transformational.
Very engaging and easy to read. It’s packed with practical, actionable tips for fatigue and poor sleep, and it genuinely helped me make changes right away. Day 77 spoke to my soul. Highly recommend!
