Oh dear! I'm sorry to hear about that. I've had to cut down on acidic drinks as I suffered from dreadful cystitis. I only have 1 coffee & 4 teas a day now & no fizzy pop. The rest of the time I drink water, milk, proper fruit juice, peppermint or fruit tea, soup, Horlicks, ovaltine, soup, oxo & Bovril & I feel a lot better on myself. Good luck!
