Well, back in July of 07 we bought a memory foam mattress, my husband suffers from CFS and i have Fibro. Here we are almost 2011 and i have been sick most of this time. I was reading something online and kept reading more and more articles.I feel like i was reliving my life for the past 3 /12 years.The mattress's produce very bad toxins. Some say the smell wears off after a few weeks and they continued sleeping on it like us. So we decided to go back to the old mattress and see how we get. The last few days i have slept in my daughters bed since she's away for the weekend and have woke up feeling great. When i look back on nights i have fell asleep on the couch and woke up feeling good. So you know im really thinking this could be the problem. Sad to say i really hope this is the problem. When i tie in everything. I started getting sick Fall of 07 a few months after buying it, bit never linked it together. I have had severe joint pains to the point of not being able to get out of bed, waking up with migraines,nose bleeds, swollen lymph nodes and just flu like symptoms. I know many that have the same type of mattress and don't have problems. But what i was reading if you have fibro your body reacts really different to the toxins. Just wondering if anyone else has a mattress like me.
