I also have this problem. There is a Urinary Incontinence Center in MD. that was doing a test with a drug that was used for depression. They found out it also worked for incontinence. I tried it ,because I was desperate, and it worked very well, but I had to stop because of one of its side effects.If you want to know more let me know. If I remember correctly it will be out on the market soon.
I'm seriously thinking about the surgery,but it may be awhile.It's good to hear info about the surgery.
