Ooh you poor things, I'm 38 weeks so past all that, agree with the feeling of having a hangover constantly!
Eating, drinking lime cordial, sherbet lemons, cream crackers, refreshers, all helped a bit. If I think of anything else I'll let you know.
My worst was with my 2nd (boy) when I actually was sick and went on til 22 weeks but my 1st and 3rd were feeling sick til 15 weeks, 1st was a girl and this is another boy so no link with sickness and gender there!
Hope you feel better soon. Being busy working helped too, I think it takes your mind off it a bit xx
