The only overpacking I do is OTC meds. I have everything anyone on board might ever need! Cold medicine, Dramamine, Imodium, Tylenol, ibuprofen, sunscreen, aloe, pepto, ambesol, benedryl, bandages, moleskin, antiseptic. You name it, I got it. I can wear outfits more than once & wash stuff in the sink but no way am I gonna be without an OTC!!
