My doc told me that fatty foods surpress the valve function, if I remember correctly. So you might try avoiding high fat foods and see if it helps.

The basic non-pharm advice is:

1. Reduce intake of fatty foods.
2. Prop up your bed a bit, probably from under the mattress.
3. Don't eat after supper.

I feel like I'm forgetting one... Ah, well. Hope something helps.

Drinking water when eating fatty foods can help too, it breaks up the fat in the stomach so you can digest it better. Be careful with any exercise that shakes your stomach around too. I suffer from it also and I mostly resort to walking to get excess energy out of me rather than risk an attack.
