Hey IG- congrats on the new job with less stress; always a good thing!
I like how you're doing new challenges as it's something I did a few years back. I started by cutting out all HFCS, then trans fats (when trans fats were the rage), then reducing beer intake (hard as hell for me). All this was before I truly found what worked for me, but those small changes were enough to spur a 40lbs weight loss.
Self-realization. I was thinking of the immortal words of Socrates, who said, "... I drank what?"
