Neil is a physics teacher from the UK but living in Bangkok, who suffered from both IBS and anxiety and noticed a connection between the two and started to research. He has been researching anxiety for the past three years, has a popular anxiety Facebook page with over 20,000 readers, and is working on his third book. The Anxiety Shift: Gut Rehab was his first book and is the link that  he researched between the gut and anxiety. The system that is in this book is the system that Neil used to banish most of his anxiety from his own life and is an excellent tool for dampening those heightened anxious feelings.
