I've been having a lot of problems during PMS, out of which sleep cycle and mood swings are the most uncontrollable and has been affecting my work as well. My sleep cycle is generally not good, but during the PMS time, it's absolutely out of control. I'm not able to sleep at night, no matter how tired I am. And when I do fall asleep, it's very difficult to wake up and get out of bed on time, it feels like I'm on a half asleep state and keep falling back to sleep and waking up every few minutes. I get irritated very easily and frequently during this time. It feels like everything irritates me,and sometimes I feel like banging my head on the wall. I can't focus on anything. Uncontrollable emotions, I feel helpless. This only happens during PMS. During and after periods I'm absolutely fine. Other issues which are usually mild- digestive problems, bloating, nausea, acne (sometimes it's severe)
