"i have been off and on this medication this last time due to losing insurance and couldn&#039;t afford it.  i got my insurance back and happily my insurance pays for it and only a copay of $10.  yes the first few days i have a headache so i slowly start taking it then once i&#039;m used to it i started them twice a day.  i love this medicine.  it curbs my appetite and the one month i have been using lost 5 lbs.  i have to make myself eat sometimes.  i have knee problems and this has helped me to lose the weight since i can no longer work out like i used to."
