Day 2 ends not feeling so great

I thought I was going to rock this juice fast and not have any detox symptoms... but today was LOW energy. (I've been sleepy for a few months now, but still with plenty of get-up-and-go in me...just sleepy (if that makes sense). But today was physically tired.. no energy to move at all). And by the end of the day, things just weren't feeling right. A little sick to my stomach (very minor), and a general feeling of unwell. Not sure if it's detoxing or what... I'll assess tomorrow if I should continue on. The outrageously low energy is new to me with juicing (normally it's not a problem... or at least it's not a problem for the first 5-7 days).. but today is only day 2! :P Come on people... really? Maybe it's just a combination of everything and my body is doing the ol' heave ho and getting rid of everything as fast as it can. Or maybe I have a brain tumor. ;) I've also been feeling pressure up around my sinuses and forehead (been feeling that for a while). WHO KNOWS! I'm doing so much more than I ever have in terms of healing... Maybe I've just never gotten this far in my healing journy before. I like that thought.... that's pleasent. I'll take it. :)
