I had a very bad bladder infection a month ago. Doctor gave me cipro for five days, did not cure me. I took D mannose , three capsules wirh one glass of water and 45 mi utes later two glasses of water or three if you can drink three. I repeated this every three hours. I kept doing this for four or five days. Second and third day I felt worse but didn’t give up because I didn’t have other option. The 4th day I started to feel better. I think the secret with D mannose is to take it and wait 45 minutes so d mannose attaches to the walls of the bladder and later when drink more water it helps to flush out all bacteria. I hope this helps. I know bladder infections are painful. I wish you feel better soon. Also I read that the powder works better than capsules.
