My doctor told me that birth control actually increases your sex drive, because you now do not have a whole lot of fear about pregnancy, so you enjoy it more. Also, gaining weight is a myth. I read that it is about equal to the number of people who actually lose weight while on the pill. I quit taking ortho novum for four months, and actually gained weight. The birth control kind of supresses my appetite a little, so maybe it is different with different people. The only thing that made me hate my last pill was the major mood changes. I was depressed and hated the world. I am not on my third day of ortho tri cyclen lo, and I really like it so far, nothing weird yet!! Hope this helped.. :)
