I've only been using the D-Mannose powder on myself for a day and a half but it seems to be helping - though I still couldn't sleep through the night. Seems like if I don't take it every couple of hours, it starts feeling worse again. I'm going to stick with it for a few days. I woke up yesterday morning at 1 or 2 am with a sudden pain and urgency - weirdly I had a dream of blood in my urine right before - and sure enough when I went, it was pinkish. Anyway, today the urgency is the worst part for me, I guess that IS the pain. I ran a low fever most of the day yesterday but that's gone today. Ted said not to drink tons of water so I'm a little conflicted on that, but I can see his point as it increases the pressure and feeling of urgency.
I also took 1TBS ACV (apple cider vinegar) yesterday once and today just once so far. I may try taking more of that if the DM doesn't work better.
In the past I have tried D-Mannose on a cat with pretty good success. That's why I already had it in stock.
