Hi,
i've done a lot of research on it, and basically it seems like a good alternative to tubal ligation, which is invasive.
Here's some of the stuff I learned:
the procedure only takes about 20 minutes, or so, and you can go home the same day. It can be done in the doctor's office, or in the hospital. Some insurance will pay part of the procedure. Most women don't experience a lot of pain afterwards, and most return to work the next day.
The recommend using an alternative birth control method for at least three months after the procedure is done, just to make sure it worked. There are some cases where the "barrier" didn't block the egg and pregnancy occured, but not many cases.
I'm thinking of getting it done because the birth control pill i'm on now, the "micronor mini pill" is making my breasts huge, and making me gain so much weight. I took the combination pill for over 20 years and suddently got high blooc pressure, so I can't take it any more. I really hate the progestin-only pill due to the side effects.
If I get the essure procedure done, i'll post my experience here.
