Hi. I have a prescription for citalopram here, prescribed to hopefully eliminate my debilitating physical symptoms the doc claims are merely due to anxiety and depression (including nausea, fatigue, insomnia, malaise, panic attacks, pms, adrenaline surges, heart palps, digestive issues, night chills, etc) -- but I am on the second day of my period (the heaviest, worst day) and don't know if I should start the citalopram today. I am also still a little skeptical that it will help and not entirely sure i should take it at all. Any advice?
