I started all-day-sickness at around 6 weeks - but only nausea. Was vomiting 3-4 times a day from 8-10 weeks. I've had a couple of days off work, but i live about 5 minutes away from the office, so some days when i was feeling really off and couldnt get out of the ladies bathroom at work, the boss would let me go home for a couple of hours, put my feet up, have a good spew, eat a tonne of food then come back in hehe

The vomiting has stopped this week and i am feeling a lot better. Still dry retching in the mornings and at lunch, but other than that i think i am finally coming good.
