Hi. I had gone through your concern. Proper treatment and control of high blood pressure are necessary. Certain routines and lifestyle modification will help you like Fix sleep schedule and stick on it No day time sleep Exercise that makes you fatigue Stress free activities and meditations Avoid alcohol and smoking Avoid heavy meal in dinner Avoid tea cofffee soft drink at night Use bed when you feel sleepy Read upto when you will sleepy No talking or use mobile in bed Calm and cool bed room All of this will help you to restore good sleep. Medicines like low dose of benzodiazapine will help.Lorazepam is safe in hypertension. Go for psychological screening because psychological stress also can lead to sleep problem.so treatment of it will resolve it. Consult psychiatrist and get help. Glad to help you further. Thank you.
