"i have been on this for 6 months and only have one issue with it. i gained 10 pounds after being on it for 1-2 months, but have been able to get that 10 down to 5. but no matter how healthy i eat or how much i exercise, i cannot lose that extra 5. other than that, i have had no issues. it has not affected my mood or sex drive, and i haven&#039;t had any headaches or anything like others have mentioned. it actually cleared up acne on my chin so i have a clear face now that the dermatologist couldn&#039;t even clear up because chin acne is usually all hormonal. from what i&#039;ve heard, if you had an abnormal (whether it be painful or irregular) period before trying this, you should not take it or it will affect you. i had a very regular period before."
