"first off, it really works. first two weeks were great - zero appetite and no side effects. but this week i&#039;ve been so sick i can hardly do anything - nausea, headache, diarrhea, slight fever, chills. not sure if it&#039;s the medicine, but going on day 4 of feeling like this, i&#039;m worried that it is :-( had anyone else had anything similar after feeling fine to start? i&#039;m down about 8 lbs and would love to stay on the medication, but not sure i can if this &quot;sickness&quot; is a result of the medication."
