Hi Dawn,
I really hope you are feeling better. I have an infrared sauna at home and love it (it really really helps my joint pain). To reiterate the posts above it is really important that you replace your minerals, salts, fluids after a sauna and build up slowly and steadily as per any chelation regime - otherwise you can end up feeling worse.
