Insomnia as a symptom of Kundalini, I would think is a definate possibility, we personally would use a wonderful balanced remedy to called TRANQUILITY and also all the INDIGO remedies in the same range..
www.phytobiophysics.com if this does not work just look on a search engine for
phytobiophysics.....these are colour/flower remedies and work on each chakra and are very very good!
