It's very odd that a doctor would blame hormones for physical symptoms like yours. I think it's more likely related to your gall stone. In which case do not try to eat chips. They have very little nutritional value anyhow and the fat and salt will make you feel worse. You would be better off taking the Sustagen and/or some broth like soup. Miso soup could be good as long as it was low in salt. If you could get your hands on some In-Liven it would be your best option.

You need to to get another opinion. And don't eat those chips.

Let us know how you go.
