"i started on this medication on july 7th 25mg at night for weight loss, the 1st night wasn&#039;t to bad, now when i take it at night i can&#039;t sleep. i just started today on twice a day some of these reviews scare me to the point that i&#039;m not sure if i want to continue taking this.  i don&#039;t have memory loss and don&#039;t want it and surely don&#039;t want my hair to fall out."
