Ive been takine it for about 2 weeks, up untill yesterday that is. the first few days taking it i had no problem, but then i started getting really bad headache's, blurred vision, nausea, and tension in my neck. then yesterday i woke up with a small rash on my chest. As the day went on the rash started spreding buy the end of the day i had a major headace, fever, and i was covered in a rash from my neck to me knees. i went stright to the doctors an he said i was having a major reaction the the drug and to stop taking it. hopefully this rash and headaces will be gone with in a few days.
