in addition, when using a heat pad don't use Hot Hands (the max temp is up to 140 degrees) and it will get there. the pads called Tostie Toes only reach a maxx of 100 degrees. use a self stick temp strip to monitor the temp. but since its summer and already pretty hot, depending where you live, you may not need to use the warmer. you should test it out and see if your body will keep it up to temp alone.

regarding using your wife's urine: on occation the lab may check for pregnancy (even in a male sample). happened to a friend and busted.

good luck!
