As the proud owner of a grouchy pouch, I can recommend drinking warm herbal mint tea--when you get up, before you eat, etc. It helps thin out and clear out accummulated phlegm or nasal discharge that can run down the back of your throat (and you might not even be aware of it, but it's common during healing). And it just relaxes and soothes you.
Are you drinking milk (lactose) products? If you are, consider eliminating them for a few days to see if that makes a difference. Are you trying to add too many foods too soon? If so, cut back so you can carefully assess what works and what doesn't at this time (it can change over the months).
Just a thought.
