aha. It's you again allergic one.
If it is happening at night it may be your washing powder. My eyes were a mess. I have a horrific pic which I could mail you so you can feel better about yourself).
I discovered it was the washing powder when we went away for a week and it cleared up. Came back got up next morning - utter mess.
mail me on [email protected] if you want to see a scary pic. It took me months to find out it was the washing powder. Am fine now.
