I have been taking guai for 20 months and have experienced only a little improvement. I recently discovered ki energy treatment provided by a Korean organization and after a month experienced improvement in energy, sleep and neck problem. The Ki healers are saying the guai might interfere and Dr St Amanda is telling me to increase the dose of guai which I did only a little and it has undone the improvement of the energy treatment. The healer who told me it might interfere had cfs and totally recovered with ki. I am totally torn about what to do. For anyone who is interested in ki. They are in 5 cities in the US and I highly recommend them. Any input would be appreciated.
