Everything is essential. I always have these medicines on deck inside my purse. Road Trips, Vacation, where ever, I believe its better to be prepared than to panic…for instance, I remember its midnight and driving down the road trying to find a CVS pharmacy before my tummy explodes, Im thinking in my head like “OMG H*ll Noooo”…from then on, I always have everything on deck. Peace of mind is the way too go, always!
