I used to get this last year after I think I had food poisoning, where I'd wake up about 1/2 hour after going to sleep with the feeling I was going to be sick, though it tended to go away if I just concentrated on my breathing; I think it was also connected to my anxiety (I'm on medication) but it pretty much went away after a while.
Since then, I've tried to be better about not eating a lot late at night (I work until about 10 at night - so I like to have something before bed) but I do have a fair few slip ups and last night I had half a packet of sharing crisps and half a pack of those Maryland cookie thins, which I know wasn't good.
Anyway, I woke up about half an hour after I went to sleep with that nauseated feeling, I turned that bedside lamp on, tried to read and took deep breathes and it did lessen enough for me to go to sleep and I feel okay this morning - though quite anxious that it will mean I will be sick (I'm a bit phobic about throwing up)
What I'm wondering is whether it was the sugar or the late night eating and what might be better for me to eat at night to stop this kind of thing happening - I'm a very picky eater, not good with fruit or veg (except apples and tomato soup :p)
Any advice anyone has would be great.
