Dr. Kendrick prescribes Metronizadole for a 21 day period. It was sufficient to clear up Snoop's problem. We also gave him egg-yolk mixed in a soup made of his regular dry food (Iam's Kitten) twice a day for that period. Snoop also has mild insulinoma so we did not add any sugar-containing additives, but you might add Nutrical to Goose's, or Pet Tinic, a vitamin supplement available from most vets.
