I have just started reading this book also and am interested in giving this a go. However, I have tried various supplements in the the past and they usually make me feel worse e.g. spacey, irritable, upset stomach. I also worry that a lot of complimentary medicine is not evidence based, so you end up experimenting on yourself with compounds that are untested and non-stardardised in dosage. Not to mention that they tend to be very expensive. Whether it is drug or a supplement I want to know if it safe and more effective than a placebo. But I guess when we are suffering we are willing to try anything if it may help. There are some supplements suggested in this book that I haven't heard of before so I think I will try them. Thanks for the info.
