often times, our body tells us what it needs through cravings, much like a pregnant woman craves odd combinations of foods.. such as pickles and peanut butter for an example.. perhaps its the vinegar in the pickles and the protein in the peanut butter.. it is more than just the taste combination. Some women crave chocolate when they are on their period.. perhaps its the antioxidant properties of the chocolate...
this may in fact be the response your body has for lack of PM now that it has had it and not had it. I have taken PM , however, have not experienced any audible (to me) voices or white noise, cravings, perhaps a bit, then again.. I am on an autonomic operation schedule ( cruise control) most of the time anyway

.. my routines often are just repetitive of the day before.. perhaps there ARE voices screaming at me and I am not paying attention?

oh wait, that might just be my boss.. never mind
