Malaria
"I&#039;m usually pretty tolerant of drugs, but this one was awful! Hot and cold flashes, sweating, abdominal cramps, headaches.The tablet form was much better. The scariest side effect for both forms for me is that my period stopped for 3 months and I&#039;ve never had any variation with that kind of thing. Felt like I was going through menopause even though I&#039;m very young."
