So sorry to hear your DH is having sleep troubles.I jerk and jump a lot myself, only the past few years since I am older now. Maybe its restless leg symdrome, I also had and still have problems with sleeping. I had been on some nasty pain meds, the Dr. has taken me off about 1 month ago, had a real bad 8 days of withdrawls, but still have some trouble with sleeping. If its nothing like above, maybe he should go to a sleep study lab and get checked out. Its not good if your body cannot get the rest it needs. Sleep helps us repair our bodies and minds. Lace
