I am flying to south/central america in june. It will be a short trip but I have 2 different meds valium and tylenol 3 that are from 2 different OP's. Will I have any hassle if they are in the original bottles? I only plan to take enough for my trip and I don't want to glump them all into 1 bottle for fear of customs wanting to see a prescription. They are valid so will I need to do anything else or just keep them in the original bottle's ?
