"i switched to this from junel fe because i was hoping to help my acne and weight gain (gained 10 pounds on junel). i only took the pill for five days but had to leave work early two days and went straight to bed by 6pm every night due to a severe headache and overall feeling of lethargy and dizziness. i felt short of breath by day two and it remained until i quit taking the pill. i also had extreme anxiety. i got severe allergy type symptoms by day two and felt feverish. i stopped taking yaz yesterday and already feel better. no headache today, no feverish feeling, no anxiety. still congested but no feeling short of breath anymore. i also noticed that i gained 2 pounds in the week i was on yaz. yikes! i have not changed my diet at all."
