I've been at this for about 5 weeks now, which I think is long enough for me to confirm that there is a marked difference in my personality on paleo. Mostly it has to do with a lack of the low level anxiety and worry that used to pervade my days. I also generally feel happier, more optimistic, and friendlier. Another thing that I never really realized is that I used to have a slight fear of people or would often feel awkward around people, especially strangers. Now I find myself striking up conversations with anyone and everyone. Rather than the extreme highs and lows, I tend to be more even-keeled and balanced. It's truly amazing!
Has anyone else experienced the same positive benefits from paleo? I'd be curious to hear your story.
