How many posts can I have in a week?

Sorry to spam you all with posts, it's just that my eyes physically hurt. I'm not sure if it's from reading alot or not sleeping well etc, but it gives me headaches to read (which is crucial right now) and is hard to focus. I'm not sure where this came from. Please pray for me. Maybe I need glasses?

Edit 3/9/11
My friends mother (Yeri Ahn) had her ribs crushed in Christchurch during the quake and is stable but critical condition. I just found out about this and would be overjoyed if you kept her in your prayers.
