birth control
"I have been on Microgestin for a few years.  For the most part my experience has been very positive: I have not experienced unusual mood swings, weight gain or changes in sex drive.  The pill also regulated my period, which had been very irregular before, and my cramps became much less painful.  After long term use, my period became lighter and finally disappeared, which makes me paranoid about pregnancy, so I use an over the counter test every couple of months.  At the same time I also became drier and drier until sex became very difficult.  However, I have been able to combat the vaginal dryness pretty effectively by making sure to stay very hydrated all day long and especially where exercise or alcohol are concerned."
