Does anyone else have this? I've noticed that even though my periods can be anything up to 8 weeks apart, my sleep/ability to function pretty much follows a four-week cycle. 1 week ok sleep (not brilliant, maybe 6 hours), 1 week appalling sleep (4-5 hours), 1 week brilliant sleep then 1 week on the decline again.
I'm fine in that during the brilliant week I am almost hyperactive: I will feel as though my heart is racing (but it isn't), I'll have manic need to be busy and productive and will feel almost hyper-aware or sensitive. Really hard to describe but it's a bit like when your ears pop after being blocked, like I hear and feel everything a bit too much in that week.
Does anyone else get this? In a way it's great as I achieve more in that week than the rest of the month but It's also exhausting and quite hard for family to deal with, when the previous week I'd have been dragging myself around unable to even have conversation because I'm so tired.
I am in the process of reading up on HRT before seeing the GO so it would be great to see if anyone has that particular issue that was eased once on the hormones
