I'm 22 weeks pregnant and no matter what I do I literally lay awake all night, I'm lucky if I get an hour in the morning after my partner gets up for work. I feel drained throughout the day but as soon as my head hits the pillow, I just can't sleep at all and I find myself getting angry. I've given up caffeine, I don't eat before bed, I only drink water so I don't get heartburn or anything. I just can't switch off at all. I asked a pharmacist for something to help me sleep and she said because I'm pregnant there's nothing I can take. Any tips guys?x
