man you can get the toewarmers at wal-mart for a buck. its sticky on 1 side allowing you to put it on the bottle. i had a digital thermometer and checked frequently. check it again before you go into the clinic, the toewarmers stay warm for about 6 hours. its not to hot to stick under you twig and berries with undies and boxers. dude this has worked for me several times. then on your way home you can smoke a fat kid for your sucess...:rastasmoke:
