Last couple of nights i haven't been able to sleep well and i am not sure why but it has honestly made me irritable and distant from my wife. Been home from Iraq for about a month and a half to two months and its been rough transitioning back and my wife and i have had a few rough patches since i have been back but we worked through them and are stronger then ever. Well its 1:30am here and my wife keeps getting up and nagging me to go to bed but i am not tired in the slightest and honestly scared to sleep because when i do sleep a bunch of Nightmares and things i would rather not re-live come up and such and so its like i am avoiding sleep. I want to tell my wife whats going on but i feel like she won't understand and she wants me to take sleep aids but i am scared i will go into one of my nightmares and not be able to wake myself up out of it. Advice?
