Sat here feeling the exact same, you are not alone. Although not helped tonight by my DH rolling over in bed and clobbering me with his elbow, and then repeatedly snoring loudly on his back - I keep pushing him over into his side and he keeps rolling back. If he carries on, he's going to get a harder shove that will take him right out of bed! I usually find getting up for a bit and doing something helps me then get back to sleep when I do go back to bed....
I am only 18 weeks and haven't had more than a few hours broken sleep a night for a good week. Starting to get grumpy which is not like me, but am normally such a good sleeper. Have also kicked the OH out as his snoring drove me nuts! Hope this doesn't last through pregnancy. Poor baby probably feels like it is on a rollercoaster, with all the tossing and turning I am doing through the night.
No advice but can totally empathise. Am 34+3 and don't think I had more than a handful of decent nights' sleeps since being pregnant. It's miserable. Comforting myself that will hopefully get better quality of sleep with newborn (albeit stil broken) as this is what happened last time. I blame the bastarding 1.5hrly pee stops which produce a mere thinpmble full of wee despite convincing me I am about to wet myself. That and the crazy dreams.
I sleep in a nest of clean clothes on the bed room floor. It is very comfy when the bed is not. Have not had it bad though just a bit of reflux and just struggling to get comfy now (am 37 weeks) also some back/rib pain. Also for some reason sleep on any floor well. I don't know if this is any use or I am just weird
I haven't had insomnia too badly, but a friend did. She spoke to her doctor who was happy to prescribe sleeping pills of some kind, not sure whether natural or not. She basically took them for a couple of days and that was all that was necessary to break the cycle. Maybe worth asking?
