I haven't slept since my boyfriend has been in jail. I'm lucky if I get two hours a night. Does anyone have any advice or tips on how the heck I can get more rest? I'm absolutely exhausted all the time. And if he doesn't get to come home next week, I probably won't sleep throughout the rest of my pregnancy.
