I'm exactly the same country I feel drugged up all the time because I'm so tired! I don't know why, I'm taking my iron tablets and drinking energy drinks but I could literally fall asleep stood up. My bleeding was heavy this morning but has seemed to of slowed down now thank god. Have you ever asked your doc why your periods don't last long? Maybe there's not enough womb lining, mine last at least 6 days but aren't always heavy
