Yeah, just dont bring a ziploc full of pills. That is suspicious. But once travelling to France I had all kinds of scrips with me. They know that so many travellers bring medications with them since lots of people have ailments of all different kinds they don't really look too hard at that unless its just extraordinary in amounts. I had about 40 Hyrdos in a pharmacy bottle, I had 30 klonipin (rivotril) in the blister packs, a big bottle of Advil (in the Advil container) and about 20 xanax in a scrip bottle. I kept all this in my carry on. I also had about 10 packs of gum. The customs guy looked at all this and said (in French) "boy you sure have a lot of gum" LOL and I said (luckily I speak a little French - the French like it when foreigners speak their language) "yeah, it's because they don't let you smoke on the plane anymore" and he said "oh right" and wished me a bon voyage!
