"i started this medication yesterday. 1st day was great, i felt alert and motivated. on the 2nd day, i could not focus very well, once i realized i can&#039;t focus i started getting stressed and then out of no where i felt great sadness come over me and cried for two hours.  this medication clearly altered my emotional state.  pros- lasts throughout the day, does suppress appetite for those of us looking to shed few pounds."
