There were some changes announced 9/6/2006 that could help. See
http://www.tsa.gov/travelers/airtravel/prohibited/permitted-prohibited-items.shtm Among other things, the TSA is permitting "Up to 4 oz. of essential non-prescription liquid medications including saline solution, eye care products and KY jelly." I would think this could include the liquid stuff like Oasis spray, but gels could still be prohibitted. I really like Brian's idea of having your friendly pharmacist (we all have one by now, don't we?) repackage an OTC product!
