I have only thrown up 3 times. My ms started about 6w+3 with feeling like I was going to be sick because I was so hungry. Then at 7w+1 the constant nausea started and has been pretty consistant each day. I am fine for an hour in the mornings then it starts and gets worse until I go to bed. I feel nauseous if I wake up at night. This morning 8w+2 I felt nauseous but by about 9.30am it tappered off and now am back to the feeling sick because I am so hungry feeling. I am not too sure whats going on and am a bit freaked out about it. I had a scan on Monday and all was good, so am praying its just a different day for me. Does your ms vary at all? I thought once you got it, it was the same until it stopped.
