I would suggest you drink plenty of fluids regularly to flush out the toxins, atleast 10- 12 glasses of water a day. Cranberry juice also might help.
Please follow good perineal hygiene. After urination, keep the perineal area clean and dry.
Ensure periodic emptying of the bladder at regular intervals. Empty the bladder before and after sexual intercourse.
Follow double voiding. At night empty the bladder. 15-20 minutes later, empty the bladder once again.This is called double voiding.
Also , it might be worthwhile to do an ultrasound
of the kidneys, ureters and bladder to rule out other causes of urinary tract infection
Hope this helps.
