Please help? I have extreme heat problems at night. Right now I sleep on ice packs. I must waken every 2 hours to change my ice pack. What do other people do? Has anyone tried the Chili Technology. Which is water running through a mattress, and you can set the temp. My trouble is that they say you must wear a cover over you to control the temperature environment. I cannot wear anything on my body all night, or I over heat. I live abroad, so I can’t use the trial period, and just return it. Otherwise, maybe it could be controlled enough to keep me from over heating? It’s difficult to explain. I’ll have ice packs under me, and fall asleep with a sheet on. The next thing I know (about an hour or less) , I am completely overheated, and my icepack has turned to a heating pack. All because of that sheet. Otherwise, the ice packs last 2-2.5 hours. Please help!?? I feel like I am exhausted, and have been burned at the stake or something!
