No sleep! :(

Hi ladies! I am due in March and for the life of me I can not sleep at night! I would think that kicking the caffeine alone would knock me out, but nope. I am wide awake most of the night! Looking back, I feel like I haven't been able to sleep since the moment that I conceived. Normally I fall asleep and stay asleep, my job usually runs me ragged. I'm so thirsty so that keeps me up on top of urinating 374637462 times a night also. (I have a bladder condition that is worsening while pregnant, as expected.) but sheesh! Yes, I'm worried and nervous and that's all normal reasons to cause the toss and turn but is anyone else experiencing this? Any suggestions?
