The NR1 skill to reduce anxiety and sleepless nights

After my “Core Meltdown” I was saddled with a dearranged autonomic nervous system (unable to sleep, high levels of arousal and anxiety). This appeared to be the result of having lived a life ‘full throttle’ without a dedicated navigation system. With the professional help of Sylvia, a very friendly, critical, and empathetic coach, I progressively gained insight how to influence my autonomic nervous sytem with several breathing excercises. In that way I was able to turn down my overstretched system and reduce the annoying feelings of arousal and anxiety. Even more, it appeared to be a powerful tool to help me sleep again. Sylvia, many thanks for your help and giving me the right tools for getting my life back on track. Ton
