"i just started on this a week or two ago and haven&#039;t had sex since so i dont know its effectiveness but i have experienced side effects. the entire first week i was nauseous for hours starting about four hours after i took it. i only puked once though. also, i have a loss of appetite. im usually very hungry all day but since i started i&#039;m never hungry. i also experienced breast tenderness and sensitivity which is not welcome since i sleep on my stomach. the nausea has gone away for the most part but that may be due to lack of eating."
