How long to recover from using YAZ

My 17 year old daughter has used YAZ for 2 1/2 years. She has now been off of it for 12 days. She's had a multitude of symptoms like many of the other posts, debilitating fatigue, migraine headaches, anxiety, panic attacks, mood swings, anger, heart palpitations, heart racing, can't walk across the room, in bed for days at a time. I won't list all of her matching symptoms but I counted 36 that match to other posts. How long does it usually take to recover once you've stopped taking it? Is there anything else other than vitamin supplements (which we will do) to help her get through this and become herself again? JF
