In recent years I have had a hysterectomy, had heart mapping and catheter ablation without anesthesia, I have only one coronary artery, my son was hit by a drunk driver and now has seizures, my other son nearly drowned and has TBI, my daughter in law has brain avm, my dad died, my aunt died, we had a house fire, we moved, I'm a former emt-i and now full time nursing student and I find I am having a great deal of trouble sleeping... I can't afford to go to a doctor. I have tried melatonin, valarian root, and benedryl. I average about 2 hours of sleep every 3 - 4 days, my mind won't shut off. I care for my Mother also. Any suggestions, I am really getting sluggish.
