ya my shit has always got threw domestic check points in the air port.. ive had my carry on's searched before, just put ur bottles/amps in your socks and roll them up good, and put the tabs in a pill bottle..
I empty out an insulin bottle and fill my stuff in there. You can get an insulin travel kit over the counter and put your pins in with it. Put all that in your carry on, and by a diabetic bracelet. Best way to come back from Mexico.
