I'm starting the Whole30 and looking forward to a challenge or two or three! I know the biggest challenge for me will be giving up chewing gum. It's been a useful tool for me when I'm in the company of friends and they are having dessert and I'm not, just to pop in a stick of gum and it'd make my cravings for sweets just disappear. I know gum is loaded with chemical goo so I'll hope that I can make it through the month of the Whole30 gum-free.
The other challenge will be no sweetener in my morning coffee. I've tried almond milk but it's not the same. Will have to give coconut milk a try.
