That's interesting. Luckily for me, Seriphos seemed to stop my crash dead in it's tracks
I was have severe insomnia then crashing from 6 to 8 pm and within a day Seriphos stopped this.
Dr Neville is probably right though. De-stressing is key.
One thing that really helps is "Slow Breathing" and "Coherent Breathing" is very similar.
I try to be aware of breathing no matter what I am doing to make sure it is nice and slow. Driving, sitting at work, in a meeting. With enough practice, you can do it with just an tiny amount of awareness.
Kind of like once you know how to drive a standard transmission you don't need to think about shifting gears. It is ALMOST sub-conscious, even though you know what gear you are in.
Best of luck.
By the way..I really like talking to Dr Neville. So nice to have time for questions and more in depth discussion than you know who with the 6 minute calls.
