I have what I suppose would be considered mild m/s as it's only nausea and no vomiting which started at 4 weeks and still comes in waves (I was 9 weeks yesterday). I've had a few good days here and there which made me excited that I'd gotten past it only for it to return with a vengeance a few days later.
I don't know how you guys do it, being that sick every day for weeks on end I really think would do me in, I mean I really have my days where I'm fed up and I only have mild nausea
