Update

Managed to get rid of cystitis by Thursday - mixture of barley water, probiotics, citridal, and Chinese herbs. Then had a hedonistic weekend in London the Saturday after. Got cystitis again on the Monday, but by Tuesday it had gone. Since then had a couple of days of lots of sex, but was all fine on the cystitis front. But now something weird going on down there - thrush-ish - then had sex on Sunday. Feeling a bit cystitis-ish now. Just glugging cranberry squash and making some barley water...
