Hope your morning sickness hasn't been as bad as hers..!
I had about 4 really bad days where I could keep nothing down and do nothing other than lie on the sofa feeling sorry for myself. Most of them at weekends though thankfully, I went home from work one day, having had to rush to the loo to throw up – when there was a client in there. Professional 😉
Mostly though it's just been all day nausea and random gagging rather than actual sickness. Seems to be pretty much gone now though.
Sorry she's got it badly, I hope it eases soon for her.
