I'll be going on my first long trip and knowing that I'll be going through almost a dozen airport security checkpoints I was wondering how people pack their various pills. I'll be taking pain killers, allergy meds, melatonin, and multivitamins all in my carry on backpack. Would it be ok to just fill those senior citizen pill containers to the max or would I need to keep it in its original bottle? Is there nothing to worry about?
