I'm a pretty light sleeper, and go through phases of waking after dreaming. THis is usually after 3 hours, then five hours, or sometimes on and off every hour or so, if it's particularly bad.
Normally it's not that bad, as I get back to sleep again, but if I'm going through an insomniac phase, which I get for a couple of months every year or so, I find it really difficult getting back to sleep, and end up sleep deprived.
Of course, a lot of the supps used for aiding sleep (inositol, B-vits, H5tp), only seem to cause me to dream more vividly, thus, waking me after them.
I wonder if anyone knows of food or supps that actually suppress dreaming, or, rather, the vividness of the dreams.

Thanks.
