It sounds like you are suffering from recurrent erosion. The worst time is usually when you first wake up - the lid can peel off the skin that is trying to heal. The best thing is to goop your eye up very well with lots of ointment prior to sleep. There is nothing else to be done this weekend. However, you may want to speak with your ophthalmologist tomorrow about more long-term solutions, such as: debridement, or micropuncture, or laser PTK.
I hope this helps and thank you.
