About 15 years ago on a holiday i picked up bali belly on the last day of 6 days in bali before flying up to Singapore for 5 days with a friend and proceeded to spend the next 5 days writhing on a bed or visiting the ivory idol with only panadol and charcoal tablets.. Good way to lose about 10kgs in 5 days and return looking like death warmed up...
So from now on, apart from my usual prescriptions meds, i take:
1 course of wide spectrum anti biotic from doc (for my recent couple of month trip i took two lots)
2 types of pain killer, one like panadol/nurofen and 1 strong, say endone (which especially in places like the US its best to have a doctors note)
1 anti nausea like maxalon or whatver the name of the one i have at the moment
1 gastro stop or immodium
1 cold and flu tablet
1 anti inflam tablet and/or gel
1 sleeping tablet type
plus a few bandaids etc...
A docotr's note is always handy as the bag can end up looking quite impressive with a few normal medications i take included...
Although of late I haven't had to really use any of them on myself but have dispensed a couple to other friends/people i meet so its their lucky break i suppose...
NB I have not succumbed yet to the wide spread obsession people on this site seem to have with lib balms, but perhaps at some point i will make it part of my kit bag of essentials?!?!?!
