"i have the dry mouth and headache. the first day it suppressed my appetite but since then my appetite has actually increased. i don&#039;t know if it&#039;s because i&#039;m about ready to start my period, or if it&#039;s because i take pain medication with it. i had lost 1 lb the first day, but none since. i have the 37.5mg tablets. i take 1/2 when i wake up and 1/2 around 2."
