I use them all the time. I have a very sensitive vagina, prone to yeast infections and easily irritated by sexual intercourse. Also I'm on the Depo shot so my hormones are all out of whack. I get a weird odor every few months and RELY on norforms to handle the job. I've had NO side effects. And coming from me, that's great. I even get irritated wen I use those rephresh ph balancing thingies. I will say that the leaking will stop. I usually put it in while I'm laying down, taking a nap, or going to bed at night so it doesn't leak out right away and can really do it's job. After a while I'll urinate (which encourages any fluids in the vagina to exit) and then shower. Most of it is out by then but sum likes to stick around. So I'll wear a panty liner/light pad for a little while n that'll catch the last of it.
