I keep an emergency IP Vanilla Crispy & an IP Chocolate Wafer in my purse at all times. Sometimes I bring an IP Brownie too. Plus I keep a jug of water in my trunk. I'll try refilling my water bottle & drinking it first, if I'm still hungry, then I'll have whichever IP satisfies. And I agree with above, please don't beat yourself up. Planning ahead works best, with good healthy food. Perfection isn't a realistic goal. ❤
