I have been meditating twice a day everyday for almost two months now. A majority of those have been guided meditations, wherein the speaker urges to 'Let go of all your effort'. I don't know if I am not sleeping enough or what, but during at least 30% of these meditations, I have woken up from mild to deep sleep. Any attempt to not sleep would mean not letting of my efforts. Am I doing something wrong, or is falling asleep a part of the practice?
