Hi there.  My wife and I recently bought the very expensive Simmons NxG Advanced Memory Foam Mattress.  We enjoyed it just fine for 6 weeksor so and then my back started hurting every morning.  I have tried sleeping on my side but I always end up on my stomach.  I have tried body pillows between the legs and anything else I can think of.  So, now it has been 3 months since we purchased the mattress and we cannot take it pack at this point.  What do I do? Do I just chalk this up as a VERY expensive lesson and get a new firmer mattress?  Is there anything I can put over the mattress we have to make it firmer on my side?  Any help is much appreciated.  I really would hate to have to toss a $2,000+ mattress after 3 months and spend more money on another mattress that may or may not be better.  Thanks!!
