With both my previous pregnancies, and with this one it's starting, too, I have really bad insomnia. I get really tired, but I cannot sleep. I try doing housework/exercising for awhile before I lay down and it doesn't help. Many nights, I stay awake until I get exhausted, in hopes that I'll just "fall out", but as soon as I lay down, I'm wide awake again. I've tried laying down shortly after DD and DS go down, and I will just lay awake for several hours, until I get frustrated, and get up again. I'm not sure if it's a hormonal thing (Guessing so, as it happened in my previous pregnancies, too), or if it's stress, or... I don't know.
Does anyone else deal with this at all?
