birth control
"While effective as birth control, I had some bad side effects.  I took Yaz for three years and had an increasing number of issues.  All the issues I contributed to something other than Yaz until reading some forums where people were having similar problems.  Some side effects I experienced were weight gain, severe depression, nightmares, severe migraines, and heartburn.  Today my doctor switched me to Aviane. I will take my first pill in about fifteen minutes so I hope that it works for me.
I think everyone needs to remember that each person's body chemistry is different so each type of medication will affect everyone differently.  I think its pretty much trial and error to find the perfect pill for your body."
