Nevermind, I figured it all out and my internet is back up to speed!
Last night it was up to 5-10 minutes to load a page and now it's back to instantaneous *sigh of relief*
Thanks for the help everyone
Edit: May as well post what I did to resolve this in case anyone else has an issue like this...
To find out my DNS servers I entered "cat /etc/resolv.conf" in my terminal and otherwise followed damgar's instructions.
