I find that when I eat too much at night my face gets bloated. Are you eating at night? You can cut back by eating broth soups or crackers at night. Are you a smoker? I find that smoking makes my face alot fuller. I am sure it is just temporary though.

I dont think its got anything to do with eating at night. Its because your glands are damaged from the bulimia and will take time to heal. Also they are used to being so overactive, they are probably still adapting to the new way.

I myself have been in recovery for 9 months, and my parotid glands seem to be worse than ever, Apart from that everything else has got back to normal
i have an appointment to see my ENT in a couple of weeks, i suggest you go to the doctor and ask to be refferred as well. The sooner the better as there will be a waiting list

It is common that yout body, specially glandules, start to react to some food or routine changes. But, if it's for your own good, you should seek a doctor. It is really important that you do it. And don't be affraid of having a nice meal.
