When does it end?

Warning: More complaining!

We are at week 11 and so far everything seems ok.  I feel absolutely horrible, but the Zofran allows me to keep down water at least.  So far I have lost 7 pounds since becoming pregnant.  The doctor sees no issue with this so far (I am guessing because I am on the "fluffy" side to begin with). Hopefully this is almost the end, I keep hearing and reading it ends by week 12 - sometimes as long as week 14.  Although my "lucky" friend Tia had it the entire time.  I am so so so hoping that is not the case.
