I've tried guided meditations (Jon Kabat-Zinn and others), listening to sounds (e.g. recordings of Tibetan bells), practicing mindfulness without guiding materials, etc. Although I've been meditating on and off for almost 1.5 years, I can't stay awake for more than 5-10 minutes, regardless of whether I'm sitting or lying down on my yoga mat.

Has anyone experienced this? Any suggestions for how I can stay awake? E.g. based on Jon Kabat-Zinn's meditation tracks, and just what I've garnered from sources so far, the aim is to become relaxed and mindful (and not so much falling asleep :P).

Thanks,
Allie
