It's not heartburn (I do have heartburn occasionally so know when I have it and when I don't.)
It's just suddenly come on, around 6pm I start to feel nauseous and it lasts until the early hours depending on whether I actually throw up or not. There doesn't even have to be any food in my stomach. Neither filling my stomach nor emptying it helps.
Is this likely to be hormones?
Does anyone els have it?
