Since about the age of 22, I have experienced major sleep problems, always during mestruation and then again during ovulation. This happens every month. What's strange is, when most women experience PMS, this is actually a "good" time for me. It's the only time of the month I feel relaxed, I sleep great, and everything's fine. Once I get my period, I'm a nervous wreck and I can't sleep for more than 4 hours a night. It kind of goes away when the period ends and returns again during ovulation, usually days 8-15 of my cycle (middle of cycle.) What could be going on here? Something hormonal? And if so, which hormone is responsible for making me so nervous and sleepless during these 2 times of the month? It's A LOT worse during ovulation. This has put me in the doctor's office about 5 times already, and they always send me home with sedatives. But I KNOW it's because of my cycle, I chart it and everything. The only time I feel normal is the 10 days before my period starts. I love those 10 days, I catch up on my sleep and enjoy life again for a little while. Once I get my period, the nervousness, restlessness, and especially sleeplessness start all over. Any advice? Thanks for any info!
