I just came back from a family reunion and I know it's going to take me weeks to undo the damage. I slept on a mattress that wiggled like jello. I tried everything to get comfortable. When I rolled from side to side I thought I was going to roll on to the floor. By the second day I could hardly move. I didn't want to say anything to my Aunt to hurt her feelings, so I am now paying the price. Hips and lower back are just awful. Do others have this problem - when traveling or whatever? Suggestions??
