"upon requesting a yaz prescription from my doctor, i was initially concerned as i was very nauseous and threw-up a few times in the morning during the first week. nonetheless, i remained on yaz and i am certainly glad that i did. i do not suffer from any acne with the exception of the couple days preceding my period (minor and unpreventable chin acne due to hormones/menstruation). it%u2019s highly effective in preventing pregnancy and i have not noticed any weight gain. in fact, i felt thinner when i first began taking it. i do not experience any physical pain or health issues (i recently turned 21, i do not smoke, and i am very slim and active). overall, yaz is great."
