I have been practice 1/2 hour active qigong movement and 1/2 hour small universal exercises, daily for almost 2 months. I feel that my insomnia has gotten worse. I have had difficulty falling asleep before starting qigong but I was able to get to sleep eventually. But for the last couple weeks the sleeplessness occurs every other day. Master Lin mentioned that qigong will help give you energy and need for less sleep. Will it cause insomnia?

Every morning when I practice small universe I always drift off to sleep. But at night when I cannot sleep, laying in bed, practicing small universe hope to fall sleep, it does not work. Why is that? Does anyone know? I would appreciate an answer to this question.
