"i started this medication on 06/03 and i&#039;ve lost 5 lbs by 06/06.  i&#039;m having a problem with jittery nerves and my stomach feels like it&#039;s churning around. i have dry mouth, drinking lots and lots of water. it&#039;s been 4 days since i&#039;ve been on the medicine.  hoping this feeling will go away soon."
