I find the large waterbottles cumbersome when traveling, shopping etc. and since the small pint bottles of water are only available in bulk, I have purchased a .5 liter collapsable water bag from a sportsgood store. I refill it from a water fountain or with sink water after going through the line. The same is available on line from platy.com. I see that they also have a neoprene cover with a 1 liter bottle. I think I will order one and just not fill it all the way until I am ready to get on the plane. I will stick on one of the bullet proof OCF stickers.

I also carry a collapsable water cup in a small zip lock. These are available where travel accessories are sold. This is good for rinsing out your mouth and for taking medicine (there is a small compartment in the lid for pills.

Has anyone had experience getting past TSA with tubes of Biotene toothpaste? They don't make travel size. I can see this being a problem because I also use sodium floride toothpaste an hour before eating, the Bioteen after breakfast and other times in the day and MI paste before bedtime. The other 2 come in less than 3 oz tubes and are RX. Do they really beleive that anyone needs 3 different toothpastes??
