you will find that your body suddenly rejects food/drinks like caffeine, meat, egg and spices. I think it's just being over protective but if you think about it, it's really a good thing.
I have gone off chicken, mushrooms, yorkshire puds, caffeine, chocolate, eggs and most meat (especially chicken which I usually love!!)
My diet at the mo consists of heinz beans/sausage, pizza, s&v crisps, ginger biscuits mash and carrots & humous!! The OH is concerned I'm not eating enough but what can you do?
