Dave and Dan are awesome people. I've followed their channel on YT for some time. I love their message!
I'm not 100% sure, but I do think that Dave went to the Tree of Life retreat to be with Dr Cousens as well as studying the books?
If anyone has Diabetes - I or II (or any chronic dis-ease)- I highly recommend you watch the DVD "Simply Raw - Reversing Diabetes in 30 Days" - This features Dr Cousens Tree of Life retreat, working with 6 Diabetic patients. The results are amazing and a true testimony to raw living.
It will give you enormous hope!
What you will also see in that DVD is that healing is an inside job ... it's not all about the food, it's an emotional journey too. You will have to face your fears and work with them .... and if you are prepared to, you will come out the other end not only dis-ease free, but a stronger, happier and more balanced person.
