Went to GP yesterday after spending 4 days suffering with cramps, upset stomach and frequent urination and 2 of those days failing to get a doctors appointment. Turned out to be a bladder infection. I have been given 3 days of antibiotics. What can I eat and drink to avoid worsening it but also to stop me losing weight? Is dark chocolate OK? Ritz Crackers? Dried fruit? I have tried eating porridge but find that worsens my upset stomach. My bladder infection is really causing me stress and I had rough night of sleep because of it.
