Just a heads up.

Whoa, that works? It doesn't, like, make 'em easier to fall off, or screw up the delivery mechanism or something?

It works. May have to run adhesive tape over the patch to keep it on, but it works. The delivery is simply through the patch barrier down a concentration gradient. Less patch on the skin, less delivery. Works with most transdermal patches that way.

Or you can just remove one of the film barriers to ensure exactly half of the dosage. 
Doesn't work with the gel patches Losty has, though.

EDIT: Never mind. Thought you were talking about cutting patches.
