hi & welcome

sorry your family is going through this ,staying awake was my prob early on, a head injury can mess with the chemical balance of the brain . plus the feelings of anxiety, de personalization, the list is long , so messing chemically, with an injured brain, should in my opinion be kept to a minimum , as much as possible, I had a very bad reaction to prozac

zoplicone has help me with sleep in low dose and only when I need it

his doctor is best placed to advise on this,as contra indications should be looked into in depth

best wishes
