Hi Wish,
So sorry to hear you're having problems sleeping.
I'm a dreadful sleeper. Always have been. I tend to live on high-alert so sleeping is a bit of a problem I also have Restless Leg Syndrome which makes it difficult for me to fall asleep.

Perhaps your sleeping problems are related purely to your recent illness. Maybe you still have some infection or a slight fever or something? If you've had cold or flu or following infection and have been taking medications, perhaps that has something to do with it as well. Over the counter meds often contain pseudoephedrine for example. Have you been on any medications at all?

Here's hoping you get back into a better sleep routine very soon. It's an awful thing not being able to sleep properly and then have to get moving early for work and such.

take care there,
Lara
