Have seen Bells palsy in cockers, but never heard of MMM
Sounds just awful. Hope the treatment works for her and she is better soon!
You can whizz up foods in the blender, mix with a little milk or water to make them easier to manage. Watered down tinned cat food is also a tempting treat. Ask your vet for a large syringe (30ml or more) so you can squirt it into her mouth (slowly and gently so she doesn't aspirate it) if need be
For my cats who can be a bit difficult about giving pills to (to put it mildly
) I melt down their pills in hot water (about 1 or 2 ml; again, ask your vet for a syringe) mix it thoroughly and fill the syringe and squirt in their mouths. Most pills dissolve and mix pretty well and if you just keep shaking the syringe until you get it in, they get most of the meds
