dear janet can someone please tell me what is meant by on time and off time.i watch my husband and he seems about the same except he dozes off if he is reading or watching tv and no one else is in the room.he stays awake if anybody is in the room with him. i wake him up and tell him to lay down so he doesn't get a stiff neck.would it be better if i left him alone? he really doesn't talk about pd except he will say he has it.he also has a tumor near the pituitary gland and doesn't want to change meds or even go to the doctor's unless they call him .all told he must be doing okay as he drives well and there is nothing wrong with his appitite.at 78 he still rakes the yard and takes the trash to the dump. Jack has always been a hard worker and still does all the odd jobs around the house... would like advice . connie tate
