I am having similar difficulties trying to sleep. I am only 7 months and she is already a ferocious kicker! I love to feel her move, but at night I can't sleep on my side (even with multiple pillows) because she will move and kick the mattress (or so it seems). I do occasionally sleep in our recliner which seems to help. I have also found just being up and not sitting helps, but you can't do that on bed rest. I am also trying to cut back on sweets in hopes that will help her rest and in turn me rest. I might try the Benadryl to help me get some sleep too...
Good Luck! I hope you have a smooth delivery!
