I carry supplies AND pack supplies! just make sure that you DON'T carry scissors on the plane (packing them is okay)...big no no...I will cut a few strips of my waterproof tape and either stick them to a plastic bag or the inside of the bag I carry my stuff in (it's a plastic lined cosmetic bag and very cute...no one would think what is inside it!!). I don't normally use the tape, but have it when travelling for an emergency "patch". Those bathrooms on the plane aren't big enough to pee, let alone change a pouch!!
The three times the amount you THINK you'll need is a good average. Don't forget there are always hospitals you can get supplies from, but it may not be what you like...and in Mexico, who knows!!!
As far as going through security, I've never had a problem, but if I ever got the "special" treatment I think they'd be more embarassed than me!! You can ask your doc for a note saying that they are medical supplies for your condition...but if you go to the Homeland Security's website you'll see that they have an exception for ostomy supplies...the UOAA.org also has a link to what you could do.
