If you are a mother-to-be, who was expecting to "glow" and "bloom" during pregnancy, but instead you find yourself with your head down the toilet for most of the day, there is some good news at last.
Like most of these things, it's not proven, but scientists reckon the hormones which make you sick could also aid babies' development.
So all that yakking could produce a brainy baby. Yippee. Unless, of course, you are one of the lucky few who doesn't get morning sickness.
In which case you will now be worrying that your baby is going to end up thick. Nobody's a winner in this scenario...
Morning sickness tends to be different for everyone – I just felt sick all the time for the first three months, but never actually threw up, although I came pretty close several times. I couldn't eat spicy food and craved bland stodge. It was a bit like having a really, really long hangover.
Other women carry on throwing up all the way through pregnancy. Their children must be geniuses.
Most mothers will tell you that "morning" sickness is a complete misnomer; they feel awful all day.
There are loads of different ways people try to cope with the problem. Some women swear by eating constantly, although that may be an excuse. Salt and vinegar crisps seem to be a favourite.
One mother I know says she couldn't stop herself being sick, so she drank pineapple juice with her breakfast so that at least it tasted better on the way back up again. Nice.
So let's hear your morning sickness stories in all their gory details – and did anything work to make you feel better?
