You will get better--and you'll be able to eat normally again. Until then, you just can't be too careful. Maalox helped me a lot when I was having trouble, because it coats and soothes. You could ask your doctor about Carafate. It is an old drug that coats your stomach and helps it heal. I take it by putting the tablet into a little medicine cup, stirring it until it dissolves, then tossing it back. It doesn't really have a taste. You can also just take it like a pill, with water. I had the Nissen surgery recently, and can't get a pill that big down.
Believe me, I understand your feelings. I am the cook as well. The Thanksgiving before last, I couldn't eat ANYTHING. My stomach reacted to mashed potatoes! I could eat about a quarter of a cup of yogurt or custard, and that was it.
Most of the time my gastritis/GERD issues have been due to medications--especially antibiotics. I have a family doctor that I've been seeing for a very long time, who knows my stomach really well. He always has me go off all supplements--(even calcium!), and any meds I don't absolutely need when I'm having a flare up. You might think about those types of things that might also be adding to your problem. The more consistently careful you are, the quicker you'll feel better. It's hard...I definitely understand.
Actually, once things get back to normal, I can pretty much eat anything I want. I just have to wait patiently until that time. If I eat or drink something bad too soon, I'll go backwards...it's not worth it. As you begin to heal, you can start adding some things into your diet, but be very careful.
Hospital diets are hopeless. Nobody will change it for you. You have to insist that you see a dietitian, and change your own diet. I recently had stomach surgery (Nissen Fundoplication), and with that, you're not supposed to drink caffeine, soda, or drink out of a straw. All those things were on my tray. Don't ever trust hopitals to provide you with the right things to eat!!
I wish you lots of luck, and hope you feel better fast!
