"i have been taking this for 5 days but my side effects are horrible. the drug is working so well i&#039;m trying to push through. first two days i had a really bad headache and was so nauseous it was really bad. the nausea left but then on the 3rd day a severe rash developed. it has been miserable. i&#039;m going to give it another day or two because my appetite is so much less than it&#039;s ever been. it&#039;s almost shocking. i have to make myself eat. really hoping the itching goes away."
