Perfectly healthy 22 year old. Started YAZ and took it fo r about 7 months. Quit because it gave me scary thoughts. Not necessarily SUICIDAL tendencies, but sick thoughts about once a month that I would get scared and cry. Was very tired and sad a lot. I quit a few weeks ago and my nipples are sore! NEVER had that happen in my life! I think my sex drive went down a bit too.
