Is tubal ligation reversible? Other b/c option suggestions?

I was thinking that it was reversible, but my doctor told me and my fiance that it isn't. But this is also an OB that works for an indian tribe too. I'm just wondering if it is reversible because we were leaning towards getting my tubes tied after I have this one, but he wants the option down the road to have another one. Anyone have any suggestions for long term b/c besides getting my tubes tied? I'm terrible at remembering pills (I do good to remember prenatals every day)
