I did a similar thing with my eyes. I was getting better and doing well and then I spent too much time on the computer and whamo! My eyes are as light sensitive as they were 5 months ago. It's been a few weeks and I have seen improvement, but it's frustrating. I have to be careful. When I used to have similar symptoms as you have, I used to set myself back for about a week when I would overdo it. I hope it's the same for you!
