I am thoroughly addicted to chewing ice. I recently found out that I am severely anemic and am now taking iron but so far it hasn't worked. My question is I just freeze all day. I work at Pepsi and have access to all the ice and soda I want all day so I chew all day and just freeze. They took my heater away from me stating it was a fire hazard. I wear long under wear under my pants, a turtleneck and sweater and I still freeze. If you freeze to please email me any hints or tip you have to stay warm.
No real help here. I too wear long johns and more than one shirt to work and usually around the house. If you eat lots of ice get used to being cold. I am fortunate enough to be able to have a heater at my desk at work it is great....
Try using a heating pad. It shouldn't be the fire hazard that your heater was but it will still provide warmth. I use one at home so that I stay warm and my family doesn't have to suffer.
