I was so tired I tried to get a normal nights sleep.  Fell asleep around 11pm and was awake again around 12:45am....too awake to sleep but feeling like crap.  Got a headache.   It's not uncommon when starting the products, it's a sign that it's working.  Here's a paragraph from their site: As with any positive dietary change, certain individuals may experience temporary symptoms, due to a variety of positive nutritional changes. These symptoms can include headaches, constipation, diarrhea, nausea and skin blemishes. Although unpleasant, these symptoms are a good sign that your body is ridding itself of toxins and pollutants and are only temporary.I think that's probably why I have the headache.  Ah well...hopefully it won't last long.  Gonna go play around for a bit and then try the sleep thing again.
