My DH sweats in bed to the point that he soaks the bed. I can deal with the sweating but in the morning/following evening there is a strong vinegar smell off the bed linen. If he exerts himself at all, walking for 30 mins, heavy lifting he is soaked. The smell is unbearable, but its not the usual BO smell. He is overweight. I can't describe it. Has anyone else come across these problems or have any advice on what I can get him to do.
