Don't know about the hormones - it might be, but as I say if you don't feel comfy taking that much painkillers, I would seek medical attention. How are you reaction to painkillers? I mean, like me, I have to take about two/three STRONG painkillers (Ibibrufen) just to feel something. I even have some prescription meds from DH's last operation that helps - sometimes. Do you get migrains??
So glad for you that MIL is going to come and help. Maybe you will feel better after having a "sleepy" day
Just thought about this: We have this headachepowers (mix asprin, paracetamol and caffien - sounds potent) that sometimes helps me get through the last part of the day, because it works faster than the tablet. I take it when, like you, are close to tears, because I HATE the taste and usually I breath in and the powder gets in my nose and I gag. It's a sad sight

PS. It sounds like I am a painkiller popper I'm not. I just get headaches constantly (heat and stress related) and suffer the odd migrain every once in a while - for those I got some gooooooood *****
