just an fyi to anyone else who gets struck down by cystitis/UTIs - you can get a kit at boots, dipUTI, which has a urine self-test comparable to what you get at the GP. you scan with a phone camera and if positive you can get antibiotics (nitrofurantoin) from the pharmacist. i woke up with a nasty sudden one this morning and i had antibis in hand by 6.30am. i used to get UTIs all the time and i wish so much something like this had been available then as i used to spend hours waiting to get prescribed! i don't work for boots or dipUTI, i'm just a serial UTI-getter and i am so impressed something like this exists as cystopurin etc did nothing for me.
