Self Control Program for Windows

Hi, I'm trying to find a similar program to the mac program Self Control. There are a lot out there but I can't seem to find one that specifically meets my needs. I want one that's free, that allows me to block any number of websites I want (I have a long list) and that allows me to block certain time periods rather than giving me a certain amount of time I'm allowed to go on the websites. Basically there are about 40 websites I would like to only be able to access between the hours of 5pm and 11pm. Leechblock allows you set time blocks to access the websites only during specified times, which is perfect, but it only allows you to block 6 websites and I need to block a lot more than that. Cold Turkey has a student option that is absolutely perfect for what I'm looking for but it costs $14 a month. Does anyone have an recommendations? Thank you.
