Questions about the Mariana

About 8 months ago i got the Mariana put in, I've tried the pill but it wouldn't work when i began taking tegratol (an antiseizure medicine). I have been told hormonal contraceptives will not work with the tegratol. I love the Mariana, but for a few weeks there it moved, i had to hold my bladder for over 14 hours (i was working during that time), causing me severe pain. I had sex a few days later and it moved the Mariana back in place. The pain was extreme. Since then i haven't had anymore problems.

I would like to know of any of you have had the Mariana (good for 5 years) or the other one (good for 10 years) put in. Did you have any problems out of them? Did you have to get them removed after a certain time? Would you get it put in again, or still currently have one?
